Hadith Q1475
وَلَوْ لَمْ يَقْدِرِ الْمَرْءُ عَلَى شُهُودِهِمَا إِلَّا حَبْوًا عَلَى الرُّكَبِ
Even if a man is only able to attend these two prayers by crawling on his knees.
Hadith 1475
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "If people knew the reward and virtue of the ‘Isha and Fajr prayers, they would surely attend them even if they had to crawl on their knees."
