تڑپ رہا ہوں بُلاوا مگر نہیں آتا
مدینے جاؤں پہ اِذنِ سفر نہیں آتا
تری ثنا سے نہ جب تک حروف تر ہوں مرے
سُخن کی شاخ پہ تب تک ثمر نہیں آتا
دلوں کا حال بدلتا ہے میرا ربّ لیکن
بغیر تیری دُعا کے عمرؓ نہیں آتا
کرم کہ ذات تری افصح العرب ٹھہری
کہ نعت لکھنے کا مجھ کو ہُنر نہیں آتا
درود گر نہ پڑھیں اِس کے اوّل و آخر
دُعائے نیم شبی میں اثر نہیں آتا
Literally Bai't means solemn assurance to do something and absolute submission to one's commands. All the believers have declared to follow the commands of Allah Al-Mighty and act upon the guideline of His Holy Prophet (P.B.U.H). In the early days of Islam, every person intending to embrace Islam use to take an oath of obedience and loyalty to the orders given by the Prophet (P.B.U.H). The person gave his hand in the hands of the Prophet (P.B.U.H). Afterwards, this sort of oath was introduced in many kinds; one of them is "Bai't Islah or Bai't Al Tuba". The Bai't is in accordance with the spirit of Islamic teachings. The scholars of Islam in majority have accepted its authenticity as discussed in the article under reference.
The use of catalytic cross-coupling methodologies for preparing aryl functionalized derivatives is an emerging field. Benzothiazole is a heterocyclic compound, weak base, having various biological activities and still is of great scientific interest now a days. Halogenated 2-aminobenzothiazoles were prepared with reported methodology. Suzuki cross coupling was done with Pd(0) and N-arylation at amino group using copper as a catalyst. The synthesis of different derivatives of 2-amino-6-bromobenzothiazole and 2-amino-6- chlorobenzothiazole were investigated. Suzuki cross coupling reactions were done with various aryl boronic acids/ aryl pinacol esters. Suzuki cross coupling gave product with good yields. Suzuki cross coupling reaction was carried out in which Pd(PPh3)4 was used as a catalyst and K3PO4 as a base. Suzuki cross coupling of 2-amino-6-bromobenzothiazole was also tested with aryl and heteroaryl trifluoroborates. Chan-Lam coupling was carried out at amino group in benzothiazole using Cu(OAc)2 as a catalyst without base, and reacted with different aryl boronic acids along with aryl trifluoroborates. Biological activities were also tested for these new series of compounds. Most of the compounds showed excellent antiurease properties. These newly synthesized compounds showed moderate to good nitric oxide scavenging, antibacterial and haemolytic activities.
