Hadhrat Mufti Saahib (RA) used to wake up at about 2:30am and engage in nafl salaah. The salaah would be extremely lengthy. At about 3:30am he would partake of sehri which consisted of a few morsels of food. Immediately thereafter he would engage in nafl salaah until Fajr.
After the Fajr azaan he would read the two sunnats of Fajr. He used to rest a while after Fajr and wake up at about 7:30am. After making wudhu he would once again engage in nafl salaah which again was extremely lengthy. Only Allah Ta’ala knows where he obtained such strength to perform such lengthy salaah at an age where he could barely stand up without feeling dizzy. He remained engaged in salaah with complete care and concentration until 9:30am. Thereafter he would listen to the Qur’aan (dhor) of a few Huffaaz and would dictate the answers to his correspondence and fataawa. This would continue till 11:00am.
Thereafter, for half an hour someone would read out the Fataawa Mahmoodiyah (which is now printed in 32 volumes al-hamdulillah.) Hadhrat (RA) would listen and correct any mistakes. At 11:30am the book Al-I’tidaal used to be read out and all the mu’takifeen would sit for the kitaab reading. This continued till about 12:00pm. Thereafter, if anyone had some special mashwarah to make, they would enter Hadhrat (RA)’s tent and speak to him personally.
Hadhrat (RA) would then make preparations for Zuhr Salaah. He performed the four sunnats after the azaan was called out. The time between azaan and jamaat was 30 minutes. His sunnats were also extremely lengthy and would end just before jamaat commenced. After Zuhr, Hadhrat (RA) would join the Khatam of Aayat-eKareema and the collective dua thereafter. Many people would then gather for bay’at and Hadhrat (RA) would initiate them. Hadhrat
(RA) would then engage in loud Zikr and would focus on those making Zikr. Thereafter, he would rest for a while.
After the Asr azaan, Hadhrat (RA) would perform his sunnats of Asr and then engage in tilaawat of Qur’aan.
After Asr, Hadhrat (RA) would sit for the kitaab reading and thereafter engage in Zikr, tilaawat and dua until Maghrib. He would drink some Zam Zam and eat some dates for iftaar. Most of the time he would drink half a cup and pass over the other half to Hadhrat Moulana Ibraheem Pandor Saahib (db), his special khaadim.
After the Maghrib Salaah, he once again engaged in lengthy nafl with great ease and thereafter joined in the meals. Most of the time, Hadhrat’s participation in meals was only to please his guests. He once mentioned, “I only sit down to eat because of the visitors, otherwise I have absolutely no desire to eat anything.” After meals, he would rest a while before the Esha azaan. After the azaan, Hadhrat (RA) performed the four sunnats of Esha and after the Fardh and Taraweeh Salaah he would participate in the Yaaseen Khatam and Salaat and Salaam. Thereafter, Hadhrat (RA) would deliver a lecture for about 45 minutes.
After the lecture, people would come to meet him, some bringing ice cream and fruit for him to eat. At about 12:00am, Hadhrat would go to rest in his tent. Some of the attendants mentioned that in that time, Hadhrat (RA) would be engaged in tilaawat of Qur’aan. Despite all his engagements and work, Hadhrat (RA) would recite one entire Qur’aan daily in the month of Ramadhaan.
