'Uthman said that he heard the Prophet, may Allah bless him and
grant him peace, say, "A person will not be harmed by anything if he says
every morning and evening 33 times, 'In the Name of Allah by whose Name
nothing in the earth or the heaven is harmed. He is the All-Hearing, the
All-Knowing.'"
Anas reported that the Messenger of Allah, may Allah bless him
and grant him peace, said, "When you call on Allah, be definite in your
supplication. None of you should say, 'If You will, give it to me.' No
one can force Allah."
Narrated Sahl ibn Sa'd said, "There are two hours in which the gates of
heaven are opened. At those times very rarely is the supplication of someone
who makes supplication rejected:
when the call to prayer has been given
and when in battle ranks in the Cause of Allah."
