فرد قائم ربط ملت سے ہے تنہا کچھ نہیں

فرد قائم ربط ملت سے ہے تنہا کچھ نہیں
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب ساتھیو! آج مجھے جس موضوع پر لب کشائی کی سعادت حاصل ہورہی ہے وہ ہے:’’فرد قائم ربط ملت سے ہے تنہا کچھ نہیں ‘‘
صدرِذی وقار!
فرد ملت کی بنیادی اکائی ہے ،فرد ہے تو ملت ہے، فرد ہے تو قوم کا وجود ہے، فرد ہے تو اس کائنات کی رنگینیاں ہیں، فرد ہے تو اس کا ئنات کی رعنائیاں ہیں ، فرد ہے تواس گیتی کے گلشن میں بہار ہے، فرد ہے تو اس گلستانِ ہستی میں نکھارہے۔
جنابِ صدر!
یہ مصرع ہمیں اتحاد کا درس دے رہا ہے۔ہمیں اتحاد کی بابت آگاہ کر رہا ہے، فردکا وجود ہی اتحاد کی بدولت قائم ہے، اتحادکا لفظ ہے ہی بڑی جاذبیت کا حامل ، یہ جس فقرے میں آ جائے اس کے معنی میں حسن پیدا ہو جاتا ہے، چند اینٹیں متحد ہو جائیں تو مکان کی تعمیر ہو جاتی ہے، چند قطرے متحد ہو جائیں تو بحر بے کنار کی شکل اختیار کر لیتے ہیں۔
صدرِ ذی وقار!
اتحاد جس صورت میں بھی موجود ہو قابل تحسین تصور کیا جاتا ہے، جوقوم آپس میں مربوط ہوتی ہے وہ ہر لحاظ سے خوش و خرم ہوتی ہے، اس کی فضاؤں میں آلودگی کا زہر نہیں ہوتا، اس کے کھلیانوں میں غیر نافع بوٹیاں نہیں اگتیں، اس کے شجر سایہ دار خزاں آشنا نہیں ہوتے ، اس کے میدان ویران نہیں ہوتے ، اس کے ہسپتال آباد نہیں ہوتے۔
جنابِ صدر!
اسلام میں اتحادِ ملی پر بڑا زور دیا گیا ہے، حدیث پاک میں ہے کہ مسلمان مسلمان کا بھائی ہے، مسلمان مسلمان کوگالی نہیں دیتا، مسلمان مسلمان کو برا بھلا نہیں...

سماجی روابط کی ویب سائٹس اور اسلامی تعلیمات

Social website is a platform that allows people to create and share different ideas, information and pictures/videos. Social websites like Facebook, Whatsapp, Twitter, Linked In, Youtube etc, allow users to intract with large number of people. In every field of life, these websites have postive and negative effects. The use of social websites make them good or bad. In this paper, we present an evolution of social websites in the teachings of Islam. Islam doesn’t against the social websites, it only condemns its negative impact or negative use.

Synthesis, Structural and Biological Investigations of Vanadium V Complexes With N and O Donor Ligands

In last two decades vanadium coordination chemistry has grasp the interest of chemists due to its importance from catalysis and medicinal point of view. Vanadium plays significant role in different biological systems, actively serving in vanadium dependent haloperoxidase and nitrogenase enzymes. It also exhibits insulin-mimetic (anti-diabetic) activity. The present study is carried out in order to synthesize new vanadium (V) complexes with N and O donor hydrazide ligands and reveal their biological importance in terms of antioxidant activities and different enzyme inhibition activities. On the basis of spectral, elemental and physical data, synthesized vanadium (V) complexes are tentatively assigned to have an octahedral geometry with two hydrazide ligands and two oxo groups forming a negatively charged sphere complex with ammonium as counter ion. This is further verified by the conductivity studies of the complexes. In synthesized vanadium (V) complexes hydrazides act as bidentate ligands and are found to be attached with O of C=O and N of NH2, and these attachments are evident from IR and NMR spectra of these complexes. The inhibitory potential of vanadium (V) complexes of hydrazides against oxidative enzymes including xanthine oxidase and lipoxygenase is determined. In addition, non-enzymatic radical scavenging activities of these complexes were also determined. Results show that hydrazide ligands (1-12) and their respective vanadium (V) complexes (1c-12c) posses scavenging and inhibition potential against DPPH and lipoxygenase, respectively. However, contrary to that uncoordinated ligands showed no activity against nitric oxide, superoxide and xanthine oxidase whereas their complexes showed varying degree of activity. It is interesting that V(V) complexes are more active for all enzymatic and radical scavenging studies reported here except for lipoxygenase enzyme which demonstrates the difference in the interaction of metal complexes with metalloenzymes. Furthermore enzyme inhibition potential of all the synthesized ligands, metal salt and vanadium (V) hydrazide complexes has also evaluated against tyrosinase, urease and carbonic anhydrase enzymes. Results obtained during the course of this study reveal that hydrazide ligands show moderate inhibition against tyrosinase, but found to be inactive against urease and carbonic anhydrase enzymes. Vanadium (V) hydrazide complexes show variable degree i.e. excellent, moderate to weak activity against all of these studied enzymes. These studies indicate that geometry of complex, nature and position of substituent groups play a vital role in scavenging and inhibition potential of these compounds and demonstrate the difference in the interaction of metal complexes with metalloenzymes. Further pharmacological and toxicological studies are required to evaluate the bioactive vanadium complexes to find out their potential for use as drugs.
