He who sets back or delays whatever He wills.
“We sent Noah to his People (with the Command): “Do thou warn thy people before there comes to them a grievous Penalty.” He said: “O my People! I am to you a Warner, clear and open: “That ye should worship Allah, fear Him, and obey me: “So He may forgive you your sins and GIVE YOU RESPITE FOR A STATED TERM:
for when the Term given by Allah is accomplished, it cannot be put forward: if ye only knew.”
