ﷺ
خالق کی عنایت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
مخلوق پہ سبقت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
منشائے خدا روزِ ازل سے یہی ٹھہرا
اللہ کی چاہت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
اک خالقِ کونین تو اِک رحمتِ کونینؐ
کیا خوب رفاقت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
سننا بھی عبادت ہے تو پڑھنا بھی عبادت
قرآن کی آیت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
قرآن کے اوراقِ مقدّس کے علاوہ
ہے لوح کی زینت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
ہر سمت یہی ایک صدا گونج رہی ہے
کونین کی وسعت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
ُحُب دار ؛ محبت سے عطا کرتا ہے عرفاںـــؔ
محبوبؐ کو رفعت ’’وَرَفَعنا لَکَ ذِکرَک‘‘
Arabian Peninsula was famous for its language expertise and linguistic expressions at the time of Prophet Muhammad (ﷺ). The poets and language experts would spend most of their lives to attain excellence in Arabic language and literature. It was during such time that a man named Muhammad (ﷺ) emerged, whose linguistic expression was remarkable, accurate and amazing. He was also quite familiar with the dialects and accents of every tribe of Arabia. It was the surprising effect of this linguistic excellence that people tagged him with different titles such as Poet, Sorcerer, Kāhin (soothsayer), Majnūn (One possessed by Jinn), and insane man with insane message. Allah Almighty revealed Qur’ānic verses not only to answer such allegations but also entrusted him to present commentary of the Holy Qur’ān to the people who would called him illiterate. This article will try to find out the Qur’ānic commentary on the linguistic expressions of Prophet Muhammad (ﷺ) as a miracle of revelation. The method of research is descriptive analytical and historical. The discussion of verses of Qur’ān and the explanations of the experts of Qur’ān through the comments of orientalists have been included to support the arguments. First Part of the paper discusses status of Prophet Muhammad (ﷺ) as an illiterate man with his remarkable linguistic expressions of Qur’ān due to which he was awarded different titles such as poet, sorcerer and insane. The second part explains the Qur’ānic response to accusations on Prophet (ﷺ) raised by the opponents. In the third part, some intellectual arguments of Qur’ān and opinions of orientalist have been discussed to support the Qur’ānic responses in favor of linguistic expressions of an “Ummi” Prophet Muhammad (ﷺ) which is followed by findings and conclusion of the whole discussion.
In the current study, we investigated the role of metallotolerant microorganisms in remediation and detection of heavy metals like cadmium and mercury. Metallotolerant microorganisms were isolated from metal polluted soil. Bacterial isolates were screened for maximum mercury tolerance and isolate exhibiting highest mercury tolerance was selected for mercury bioreporter construction. Fungal isolates were screened for cadmium tolerance and organic acid production to select most putative strains for heavy metals bioremediation through bioleaching and biosorption. Selected bacterial and fungals isolates were identified by 16S rRNA and internal transcribed spacer (ITS) sequence phylogenetic analysis, respectively. Optimal growth conditions like pH and temperature of selected isolates were also studied. Carbon source was optimized to produce maximum amount of various organic acids that were characterized and quantified through high performance liquid chromatography (HPLC) and applied for leachig of heavy metals from metal contaminated soil. Elemental analysis in the entire study was carried out through atomic absorption spectroscopy. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) was performed to evaluate biosorption of cadmium by selected fungal strain. The localization of taken up cadmium by resistant fungi was studied through transmission electron microscopy (TEM) and electron energy loss specroscopy (EELS). The mercury resistant bacterial isolate DWH4 was engineered to serve as a bioluminescent bioreporter for mercury toxicity by linking its merR-like gene and promoter sequence to a reorganized luxABCDE gene cassette from Photorhabdus luminescens through recombinant DNA technology. A total of 10 bacterial and 13 fungal strains were isolated from soil samples collected from Misri Shah and Daroghawala. Out of 10 bacterial isolates, strain DWH4 exhibited highest tolerance to mercury and was selected for construction of mercury bioreporter cell. Among 13 fungal strains, isolate FMS1 was observed to produce maximum concentration of organic acids and was selected for bioleaching of metals. Whereas isolate FMS2, a highly cadmium resistant isolate was selected for cadmium biosorption. Sequence analysis of the 16S rRNA of bacterial isolate DWH4 was 99% similar to Enterobacter cloacae (MK500875). Sequence analysis of internal transcribed spacer regions indicated that fungal isolate FMS1 has 99% similarity to Aspergillus tubingensis (MK026408) and FMS2 was 99% similar to Penicillium chrysogenum (MH865997). The bacterial strain DWH4 could grow at wide range of temperature (20–40°C) and pH (6–9) with optimum growth at 30°C and pH 7.0. The fungal strains could grow at wide range of temperature (15–40°C) and pH (3–12) with optimum growth temperature 30°C and pH 5.0 and 6.0 for A. tubingensis FMS1 and P. chrysogenum FMS2, respectively. Three organic acids were produced with highest concentration of gluconic acid (263 mM) followed by oxalic acid (22mM) and fumaric acid (0.34mM) at day 12 and sucrose was considered as the ideal carbon source. The highest leaching efficiency with organic acids from A. tubingensis strain FMS1 was observed for cadmium (58%), cobalt (53%) and nickel (52%) within 28 days. Cadmium removal capacity of P. chrysogenum strain FMS2 was observed 49% in 15 days. Distinct white patches were seen in SEM with clear peaks of cadmium in EDX analysis of white patches indicating biosorption of cadmium by P. chrysogenum strain FMS2. The TEM and EELS of P. chrysogenum strain FMS2 revealed cytoplasmic localization of cadmium. The constructed bioluminescent bioreporter for mercury detection, designated as E. cloacae strain DWH4lux, detected mercury (HgCl2) at a minimum concentration of 0.2 µg/L with a linear response profile being maintained between a range of 0.4–1600 µg/L (R2 = 0.9604) with a peak bioluminescent response occurring within one hour after exposure. No significant synergistic or antagonistic influences were observed on the bioluminescent response by other contaminating metal elements. E. cloacae strain DWH4lux was also demonstrated to detect mercury effectively in artificially contaminated water sample with linear correlation (R2=0.9623). This study provides new insight into the recruitment of metallotolerant bacteria from environmental samples for mercury bioreporter development and their potential for in-field biosensing applications. The biosorption and bioleaching ability of the newly isolated fungal strains can also be helpful in redemption of polluted soil especially with trace toxic metals such as in case of compost and sewage sludge and bioremediation of industrial effluents containing cadmium to minimize its release to environment.
