خدمتِ خلق

خدمت خلق
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اساتذہ کرام اور میرے ہم مکتب شاہینو!
آج مجھے جس موضوع پر اظہار خیال کرناہے وہ ہے:’’خدمت خلق‘‘
صاحب صدر!
خدمت خلق ایک ایسا جذبہ ہے جس سے معاشرہ میں اخوت، ہمدردی اور بھائی چارہ کار جحان پروان چڑھتا ہے، مرجھائے ہوئے چہرے کھل اُٹھتے ہیں ، افسردہ دلوں میں خوشی و مسرت کی لہر دوڑ جاتی ہے۔
صدرِذی وقار!
خدمتِ خلق کا جذبہ رکھنے والا شخص کبھی حالات کے تھپیڑوں سے گھبراتا نہیں، جملہ امور کی انجام دہی سے سر خرو ہوتا ہے، پژمردہ دلوں کی ہمدردیاں اس کے ساتھ ہوتی ہیں اور یوں وہ ہر میدان میں کامیابی و کامرانی کے گھوڑے دوڑاتا ہوا آگے بڑھتا جا تا ہے۔
جنابِ صدر!
خدمتِ خلق حقوق العباد میں سے ہے، اور حقوق العباد کی ادائیگی اسلامی عبادات کا ایک اہم جزو ہے، حقوق اللہ کی معافی کا امکان بہرحال موجود ہے لیکن حقوق العباد کی ادائیگی کے بارے میں باز پرس ہوگی۔
صاحبِ صدر!
خدمتِ خلق کے لیے انفاق فی سبیل اللہ کی عظیم صفت سے متصف ہونا انتہائی ناگزیر ہے، مال خرچ کرنے سے عوام النّاس کے قلوب میں مخیر حضرات کی عزت میں اضافہ ہوتا ہے اور یوں محبت کی فضاء پروان چڑھتی رہتی ہے۔
جنابِ صدر!
خدمتِ خلق کے مختلف انداز ہوتے ہیں ، والدین کی خدمت، اساتذہ کی خدمت ، ضعیف حضرات کی خدمت، کمزوروں اور ناداروں کی خدمت، بے کسوں اور کسمپرسوں کی خدمت، اصدقا و اقربا کی خدمت، ہمسائیوں اور عزیزوں کی خدمت، یہ سب خدمت خلق سے ہی ہے۔
لیکن جنابِ صدر!
وہ لوگ قسمت کے سکندر ہیں ، مقدر کے دھنی ہیں جوطلباء کی خدمت کرتے ہیں، تو ان کے علمی میدان میں...

دین کامل اور اختلاف: روح المعانی کی روشنی میں ایک تحقیقی جائزہ

The word "Ikhthilaf" refers to such an approach and way of conversation in which one scholar disagrees with another scholar. Islam being a perfect religion bars its followers from developing mutual conflicts. Islam has clearly stated that Muslim Ummah should not have differences on the basis of opinions in vivid injunctions. Such dissension has been placed nowhere in Islam. Disputes may only arise in case of secondary and vague injunctions. In such situations, each jurist considers himself as right. Such divergence, in the secondary issues based on argumentation and within the ambit of Qur’ān and Ḥadith, is not contemptible one but is the source of blessings due to the depth of knowledge of the jurists. Because of such conflicting opinions, jurisprudence and religious injunctions have the power of adaptability in accordance with the demands of the changing times. In the matters of jurisprudence, establishing consensus on the basis of argumentation must not lead to sectarianism, prejudice and hatred. True jurists have tried their level best to protect Muslim Ummah from sectarian disputes. Among such jurists we have Allama Alusī, the author of Tafsīr Rūḥ al Ma’ānī, as one big contributor. Tafsīr Rūḥ al Ma’ānī is the solid proof of his authentic and deep knowledge. It has a combination of reported sayings and exegesis of consents.

Initial Public Offering Valuation Dynamics, Evidence from Pakistani Capital Market

The thesis examines the valuation dynamics of Pakistani Initial Public Offerings (IPOs): their practices, motivations and implications. This study examines the pre-IPO valuation dynamics and the post-IPO price performance paradigms using 88 IPOs floated from 2000 to 2016 on the Pakistan Stock Exchange. The main objectives of this study includes: (1) to provide insights of preferred valuation methods when valuing IPOs, (2) to compare the bias and accuracy attached to each valuation methods, (3) to provide the usefulness of prospectus information on the initial valuations, the underpricing and the long-run underperformance, and finally, (4) to validate the long-run underperformance using calendar-time approaches. The binary logit model, the signed predictcion errors (SPE) and the absolute prediction errors (APE) were used to explain the choice, bias and accuracy attached to each valuation methods respectively. The accounting-based valuation model was used to estimate the impact of fundamental, risk and signaling factors on the post-IPO performance. The capital asset pricing model (CAPM), Fama-French three- (FF3F) and five-factor (FF5F) models were used as robust measures to affirm the long-run underperformance anomaly. The findings document that the Pakistani underwriters repeatedly used dividend discount model (DDM), discounted cash flow (DCF) model and the comparable multiples valuation methods when valuing IPOs. The findings of SPE reveal that the DDM and DCF methods seem to be unbiased value estimators than the comparable multiples. The findings of APE document that the DCF produce more valuation accuracy than the other valuation methods. The average underpricing of 32.85% was observed in the Pakistani primary market. This research extends the underpricing analysis in various aspects such as: (1) the level of underpricing was negatively related to the firm size, (2) the underpricing of IPOs issued in the hot-issue market was significantly higher than the IPOs issued in the cold-issue market, (3) the underpricing of IPOs issued through bookbuilding was lower than the IPOs issued through the fixed price auction, (4) the underpricing of privatization IPOs was higher than the underpricing of non-privatization IPOs, (5) the underpricing of survivor IPOs was higher than the underpricing of non-survivor IPOs, XI (6) the IPOs offered in the Oil & Gas and Chemicals sectors produce more underpricing than the other sectors. The finding of initial excess returns (IER) regression analysis reveals that the earnings, financial leverage, efficiency risk, firm beta and the underwriter reputation were the key determinants to explain variation in the level of underpricing. In the long-run returns (LRR) analysis, the buy and hold abnormal returns (BHAR) produce negative returns of -23.52% and -65.22% in year 3 and year 5 respectively. On the similar pattern, the cumulative abnormal returns (CAR) produce negative returns of -24.62% and -29.37% in year 3 and year 5 respectively. This study extend the long-run performance analysis in various aspects such as: (1) the IPOs issued in hot-issue market produce more negative returns than the IPOs issued during coldissue market, (2) the Automobile & Electrical Goods sector IPOs produce worst negative returns, while the Modaraba & Foods sector IPOs outperform the market in the long run, (3) the privatization IPOs outperform the market in the long run than the non-privatization IPOs. The finding of LRR regression analysis reveals that the book value of shareholder’s equity, earnings, capital availability risk, firm beta, underwriter reputation, the percentage of shares offered and initial excess returns were the significant determinants that explain the variation in the long-run returns.In the Calendar-time approach, the negative values of intercepts of CAPM, FF3F & FF5F validate the negative performance in the long run. The market risk premium was the most significant determinant in all asset pricing models, while HML-value factor (in equally-weighted FF5F) and CMA-investment factor (in value-weighted FF5F) were also significant determinants in the Fama-French five-factor models. This study is one of the few studies in IPO valuation literature that is being accomplished in a growing and transforming from loose regulated capital market to synchronize the state of affairs and first in Pakistan to investigate the explanatory power of prospectus information on IPO valuation dynamics.
