The Holy Quran and the Hadith have given commands at various places to guide people on to the right path. It has been declared that Muslims should worry about the reformation of the whole of humanity. It is mentioned in Surah Nahl:
Invite towards the path of your Lord with wisdom and refined exhortation and (also) argue with them in a most decent manner. Surely, your Lord knows well the one who strayed away from His path, and He also knows well the rightly guided. Surah Nahl (16:125)
Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) founded “Anjuman Islahe Musalmaanan” to improve the manners and etiquette of Muslims. (Matla ‘Ul Anwaar, Pg. No. 52; Anwaar Ul Anwaar, Pg. No. 88)
He declared usage of wine, drugs, etc. as a punishable offence. He gave orders that all wine shops be transferred to the outskirts of the city. It was forbidden to open wine shops on religious and auspicious occasions. (Matla ‘Ul Anwaar, Pg. No. 52, Anwaar Ul Anwaar, Pg. No. 88)
Even in Ramadhan, functions would go on during the daytime. Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) forbade that. Hotels would be open during the day. Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) gave orders that they should be curtained during the day. (Matla ‘Ul Anwaar, Pg. No. 100; Ma’arif Ul Anwaar, Pg. No. 14)
In the days of the Nizam, the weight measures were not identical in the whole kingdom. Thus, at the time of buying or selling, there would some discrepancy in the weight demanded and in the weight delivered, although the Shariah declares this as a serious sin. The Ummah of Hadhrat Shu’aib (May peace be upon him) was punished because of this only. Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) arranged for the weights to be standardized and thus checked the evils that were taking root because of this. (Matla ‘Ul Anwaar, Pg. No. 58; Anwaar Ul Anwaar, Pg. No. 106)
