یہ تیر و تیغ ہیں کیا اور کمان کیا شے ہے؟

یہ تیر و تیغ ہیں کیا اور کمان کیا شے ہے
تری نظر کے مقابل یہ جان کیا شے ہے

گزر رہا ہوں مسلسل جو میں عذابوں سے
مجھے بتائو کہ پھر امتحان کیا شے ہے

ہزار جان سے تجھ پر نثار میں جاناں
تری خوشی کے لیے ایک جان کیا شے ہے

کسی بھی طور سے آباد یہ نہیں ہوتا
الٰہی! میرے یہ دل کا جہان کیا شے ہے

ہر ایک درد کا مارا قرار پاتا ہے
قسم خدا کی ترا آستان کیا شے ہے

افتاء كے فضائل قرآن و حدیث كی روشنی میں

To derive and discover the hidden solution to problems regarding every walk of life, according to the teachings of Islam is called Ijtihad and to convey this solution (answer) to the people concerned is called Ifta. Answers to some queries have been directly given by ALLAH ALMIGHTY Himself Then Allah gave the responsibility to his beloved Prophet Muhammad (SA W) to explain & enlighten the people according to the will of ALMIGHTY ALLAH as Quran And then the same responsibility transfers to the eminent religious scholars (Muftis) who are the true inheritors of the Holy Prophet (SAW) Mufti acts as the deputy of the Holy Prophet (SA W) and holds a very high, important & sensitive position of guiding the people towards Islamic teachings. That is why it needs high care, piety & skill. In the given article the reality, importance and virtues of this highly important position have been enlightened

Removal of Synthetic Dyes from Aqueous Media Using Biocomposites

Wastewater which is produced from different textile industries is also the major cause of water pollution. In present research work, the optimum conditions of biosorption experiments for the elimination of synthetic dyes were determined by doing batch and continuous study. The optimum pH for getting the maximum biosorption of four selected acid dyes (ADG-180, AO-RL, ANB N-RBL and ATB E-2G) was observed in acidic range (2-6) while the 0.05 g/50 mL biosorbent dose (PPy/SB, PAn/SB, PPy/Ch, PAn/Ch, PPy/St and PAn/St; PPy/RH, PAn/RH, PPy/Ch, PAn/Ch, PPy/St and PAn/St; PPy/PH, PAn/PH, PPy/Ch, PAn/Ch, PPy/St and PAn/St andPPy/CS, PAn/CS, PPy/Ch, PAn/Ch, PPy/St and PAn/St ) was determined as optimum dose for the removal of all four selected acid dyes respectively. The equilibrium was attained within 45-60 min for all selected biosorbents for the elimination of selected acid dyes. The optimum initial dye concentration was observed in 125-150 mg/L range to get maximum acid dyes elimination using different types of selected biosorbents. The optimum temperature for getting maximum removal of all selected acid dyes was observed as 30 ºC and reduction in biosorption potential of all biosorbents was investigated by temperature rise. It showed the exothermic nature of all biosorption processes that engaged in elimination of selected acid dyes. Langmuir and Freundlich biosorption equilibrium isotherms showed satisfactorily fitness on biosorption data where as the pseudo-first-order and pseudo-second-order both demonstrated satisfactory fitness on experimental kinetic data. Various thermodynamical parameters were determined to know about nature and feasibility of biosorption. Biosorption capability of selected efficient biosorbents for their respective acid dyes was reduced significantly by surfactants/detergents presence in acid dye solution. Maximum desorption was achieved using 0.5 N NaOH. In column study; 3 cm, 70 mg/L and 1.8 mL/min were observed as optimum bed height, inlet initial dye concentration and flow rate for attainment of highest biosorption of ADG-180, AO-RL, ANB N-RBL and 90 mg/L for ATB E-2G dye. The biosorption study of real textile effluents was also carried out for the application of this technology on practical scale. The characterization ofprepared biosorbents was done by FT-IR, thermal analysis and SEM which provided significant information about thermal stability, active binding functional groups and surface morphology.
