Whilst Hadhrat Shaikh-ul-Hind Moulana Mahmoodul Hasan (rahimahullah) was living in Deoband, on the day of jumu`ah, he used to go to the river to wash his clothes. Thereafter, he would take a bath whilst his clothing dried up. He would then wear the moist clothes and walk towards the musjid at a time when the azaan was about to be called out. As the azaan would be called out, he would hasten his steps in order to practise on the aayah:
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا نُودِىَ لِلصَّلَوٰةِ مِن يَوْمِ ٱلْجُمُعَةِ فَٱسْعَوْا۟ إِلَىٰ ذِكْرِ ٱللَّـهِ وَذَرُوا۟ ٱلْبَيْعَ ۚ ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ ﴿٩﴾
(When the azaan is called out for the Jumu`ah Salaah, then hasten towards the zikr of Allah Ta`ala.)
