ﷺ
سیرِِ افلاک کو جائیں گے خلا ڈھونڈیں گے
اپنی پرواز سے کچھ لوگ خدا ڈھونڈیں گے
کچھ نہیں پائیں گے یہ شہرِ صبا کے باسی
رب کو سورج کی شعائوں میں بڑا ڈھونڈیں گے
پتھروں کو کبھی پوجیں گے تو آتش کو کبھی
بے وفائوں سے وفائوں کا صلہ ڈھونڈیں گے
روشنی پھیل چکی نورِ حرا کی ؛ پھر بھی
آتشِ وادیِ سینا میں ضیاء ڈھونڈیں گے
گردشِ وقت سے اوراق ہیں بکھرے بکھرے
ایسے تحریف شدہ نسخوں میں کیا ڈھونڈیں گے
شہرِ خاموش میں جا کر یہ صدائیں دیں گے
ماہیِ آب کو صحرائوں میں جا ڈھونڈیں گے
نکہتِ بادِ بہاری سے چھڑا کر دامن
بادِ صر صر میں یہ خوشبو کی فضا ڈھونڈیں گے
قافلہ راہ میں اخلاص کا لُٹ جائے گا
راہزن لوٹ ہی لیں گے جو بھلا ڈھونڈیں گے
راہبر راہ میں رہ جائیں گے ہر راہی کے
راہ جب آپؐ کی راہوں سے جدا ڈھونڈیں گے
نورِ عرفانؔ خدا اُن کا مقدّر ہے جو لوگ
’’آپؐ کی سیرتِ اطہر سے ضیاء ڈھونڈیں گے‘‘
Imam Khattabi is considered as a glorious scholar of the fourth century. He has written several books in various scholarly traditions. One of them an important book is "Ghareeb ul Hadith". In this, he has not only interpreted the difficult words but also referred to as Ayaat, Ahadith and verses etc. Then, he also described the jurisprudential commandments existed in these Ayaat and Ahadith. Furthermore, in many places, hadith terms, legal maxims and wisdom of law are also part of this book. This book also holds a significant correlation with knowledge of Imam Khattabi's teachers because he mentioned the ahadith and sayings of scholars with his own chain. Due to these qualities of this book, not only did the scholars of language use it, but also magnificent mohaddiseen, jurists, explainers and researchers have also quoted it in their own books. Of course, it will not be unwise to say that like previous scholars and mohaddiseen this book is also important and need for today's scholars.
Recent data from 1000 Genomes Project suggest that human genome has large number of variations. While some of the variations in human genome are tolerated others result in pathogenic consequences. Consanguinity increases the probability of inheriting the variants in homozygous state in children that result in abnormal phenotype. Familial disorders are relatively prevalent in Pakistani population where consanguineous marriages are common practice. In this study, 12 inbred families belonging to various regions of Pakistan and inheriting different genetic disorders were sampled for molecular genetics analysis. Three different mutant gene identification strategies namely STR mapping, SNP array and whole-exome sequencing were used, either separately or complementary to each other. Linkage analysis of candidate genes/loci was done by STR markers and SNP genotyping. Families linked to the candidate genes were Sanger sequenced to identify causal mutations. Families excluded to reported loci were subjected to whole exome sequencing and if required to CytoScan® HD array for copy number variation detection. A series of filtering steps were followed to narrow the spectrum of variations down to a single functional variant among the several thousand variations. This study reports on three novel and six reported mutations responsible for causing familial diseases. A novel mutation, each in a family with hyponychia, Cenani-Lenz syndrome and spastic paraplegia 3A was found. Additionally, evidence were found for polymorphic initiation codon (p:M1I) in RSPO4 gene and for autosomal recessive inheritance in spastic paraplegia 3A. Whole-exome sequencing technology was successfully applied for gene identification in autosomal recessive and autosomal dominant disorders. Specific diagnosis of; spastic paraplegia 3A, pseudoachondroplasia, generalized lipodystrophy using variants derived by exome sequencing suggest that it has a dual role of mutation identification in heterogeneous disorders as well as a diagnostic tool in clinically overlapping phenotypes. The findings of current investigations will set the basis for establishing carrier screening and prenatal diagnosis to control the disease as well as for the better understanding of disease pathways.
