سبعۃ اَحرف و قراءاتِ قرآنیہ ؛ایک تحقیقی جائزہ A Research Review of Sab‘a Aḥraf and Recitation of the holy Qur’an in different ways

“This Quran has been revealed in seven different ways; so, recite it in the way that is easier for you.” This hadith is Recurrent in meaning. The narrator Imam Abu Ubaid Qasim Bin Salam (R.A) has elucidated its recurrence. Imam Abn-e- Jouzi (R.A) has collected all its ways in a Journal. What is meant by “Seven Words” in this Hadith? It has been a controversial point among the ulemas and scholars. And no doubt, it has been regarded as the most difficult debate of Uloom-ul- Quran. There have been severe controversies in this regard, so far as Allama Ibn-e - Arabi has mentioned thirty-five sayings. Some of them are as following: Some think these are the ways of recitations of seven famous Qaries. Some think that it means all the ways of recitations. But “Seven” does not means the number 07, because in Arabic language, it is used to describe the plenty of something. Qazi Ayyaz from Earleir Ulemas had the same opinion, while in the later period; Shah Wali-Ullah also had the same views. Some think that it means seven dialects of Arab Tribes. Imam Abu Hatim Sajestani (R.A) determined the name of these languages. They are Quraish, Hazial, Teem, Al-Rubab, Azd, Rabbia, Hawazan, and Saad bin Abi-Bakar. Hafiz Abn-e- Jareer Tibri (R.A) agreed to this school of thought. The fourth famous saying is that of Imam Tehavi (R.A.) he says that although he Holy Quran has been revealed in the dialect of Quraish. But it was difficult for the people of other tribes, which came of different areas of Arab. That is why, in the beginning, they were permitted to recite the Holy Quran in their local languages, and the words or ways were determined by the holy prophet (P.B.U.H) himself. Later, it was prohibited. There remained only the one way of recitation in which the holy Quran was revealed. HAzrat Sufian bin Aiena (R.A), Abn-e-Wahab (R.A) and Hafiz Ibn-e- Abdul Bar (R.A) agreed to this opinion. Famous interpreter Allama Nizamul Din Nishapori (R.A) says that it means the following differences in the recitation. Differences between Singular and Plurals Differences between Muscular and Feminine Differences of the causes of Araabs          Differences of Morphology (Formation of Words) Differences of syntax (Sentence Structure)           Differences of the ways which changes words Differences of dialects Allama Abn-e- Qutaiba, (R.A), Imam Razi Qazi (R.A) and Abu Bakar(R.A) and Abn-e Aljuzri (R.A) also adopted this saying of Allama Nisahpuri.(R.A).

Isolation and Characterization of Novel Indigenous Fungal Strain and Optimization of Cellulase Complex for Hyperactivity

The recent research is highlighted the fungal species screening for cellulase production using agricultural waste materials, rotten fruits and vegetable. The purpose of this study was to investigate hyper-production of cellulase complex from screened indigenous local strain of Aspergillus tubingensis IMMIS2, extracted from rotten tomato. Congo red test and zone of clearance method were used to confirm the cellulase complex production from this novel isolate of Aspergillus tubingensis IMMIS2. Three Aspergillus species and all Trichoderma species revealed cellulase production. Aspergillus tubingensis IMMIS2 revealed maximum beta-glucosidase production (78±0.4 µg/mL/min) as compared to exoglucanase and endoglucanase and selected for further study.Corn stover revealed maximum cellulase activity (81±1.5 µg/mL/min) after screening six substrates. Aspergillus tubingensis IMMIS2 is a filamentous fungal strain and its cellulase activity was measured on carboxy-methyl cellulose (CMC), cellulose powder, and filter paper used as substrates with Dinitrosalicylic acid (DNS) method. The optimum temperature, pH and incubation time were analyzed to be 40 ºC, 4.8, 96 hours with cellulase activity of 86.4±2.1 µg/mL/min produced from Aspergillus tubingensis-IMMIS2. Crude cellulase revealed maximum activity (112 µg/mL/min) with Response Surface Methodology (RSM) using 40mm mesh size substrate, 8g substrate, 80% moisture, 5mL inoculum, 0.5g urea, 0.1g KCl, 0.1g CaCl2 and 0.06g MgSO4 using Aspergillus tubingensis IMMIS2. Optimization of cellulase production through RSM revealed that most of the organic and inorganic parameter had significant impact on cellulase production using Aspergillus tubingensis IMMIS2. Cellulase revealed maximum activity (116 µg/mL/min) with Taguchi method using 80mm mesh size substrate, 5g substrate, 50% moisture, 3mL inoculum, 0.1g urea, 0.2g KCl, 0.3g CaCl2 and 0.01g MgSO4 using Aspergillus tubingensis-IMMIS2.Optimization of cellulase production showed that some parameters had non-significant impact on cellulase yield. Ammonium sulfate precipitation and dialysis used for partial purification of cellulase and quantity was confirmed by Biuret method. The purification factor increased from 2.12 to 5.14 with ammonium sulfate dialysis and gel filtration chromatography. Characterization of cellulase revealed that maximum activity (130.5±0.43 µg/mL/min & 133.5±0.35 µg/mL/min) was achieved at pH 4.5 and temperature 40ᵒ C, respectively. The SDS PAGE results confirmed that molecular weight of cellulase was 76 kDa. Immobilization technique was applied to enhance the stability and catalytic activity of cellulase. The immobilized and free cellulase characterization proved to enhance the thermo-stability to 82 % at 75 °C as compared to free cellulase enzyme after 26 h of incubation. Immobilization through xerogel matrix and calcium alginate incredibly increased the catalytic activity of cellulase than that of free enzyme. Cellulase activity was decreased after the 20th day of incubation of the both immobilized surfaces (calcium alginate & xerogel). Maximum cellulase activity was achieved at pH 4.5 (174 ± 0.3 µg/mL/min) and temperature 45 °C (179 ± 0.4 µg/mL/min) for xerogel matrix. Xerogel immobilization method revealed the lowest Km value as compared to free and calcium alginate immobilization. Calcium alginate and xerogel matrix immobilization increased tolerance capacity of cellulase to 75−82 % against activating agents / inhibitors like Mg+2, EDTA, SDS and Hg+. Xerogel and calcium alginate immobilization revealed good fruit scarification and hence immobilization method could be a good candidate for food industry. Cellulases are employed in food, textile, biofuel, feed and dairy industries in Pakistan.
