SubhannaAllah, a brother being treated for cancer prays on time even with his difficulty and IV attached. I ask you by Allah, when you see pics like these, do you love prayer this much that you would never leave it or let alone be late for it in your most difficult time??
Allah described the believers for their ability to preserve prayer through all circumstances and for it, He gives a great reward!
"And those who [carefully] maintain their prayer: They will be in gardens, honored." [70-34:35]
Subhanallah, what excuse do we have?
