When Hafiz Hasan Ali (rahimahullah) made sajdah, he would arise after a very long time. Once, someone thought that he slept away whilst in salaah, so he kicked him from the back. He woke up from sajdah and recited, “Inna lillaahi wa inna ilayhi raaji‘oon. Did I fall off to sleep? O no! How can I fall off to sleep and spoil the salaah of the people?”
One day someone insistently asked him, “Why do you make such a long sajdah?” He replied, “When I go into sajdah and intend to wake up, I think to myself, “Let me recite one more Subhaanallah, perhaps I may never get another opportunity to make sajdah again.”
Allahu Akbar! What a level of consciousness with respect to the presence of death! If only we could also be blessed with this condition. (Malfoozaat of Faqeeh-ul-Ummat Vol 2 Pg 482)
