CHAPTER: SUPPLICATION SHOULD BE MADE WITH CONVICTION AND WILL
No. 6477
Anas reported Allaah's Messenger (sallAllaahu alayhi wa sallam) as saying: When one of you makes supplication, he should supplicate with a will and should not say: O Allaah, confer upon me if Thou likest, for there is none to coerce Allaah.
No. 6478
Abu Huraira reported Allaah's Messenger (sallAllaahu alayhi wa sallam) as saying: When one of you makes a supplication (to his Lord) one should not say: O Allaah, grant me pardon, if Thou so likest, but one should beg one's (Lord) with a will and full devotion, for there is nothing so great in the eye of Allaah which He cannot grant.
No. 6479
Abu Huraira reported Allaah's Messenger (sallAllaahu alayhi wa sallam) as saying: None of you should say to Allaah (like this): O Allaah, grant me mercy, if thou so likest. The supplication (of his) should (be permeated with) conviction (that it would be accepted by the Lord), for Allaah is the Doer of (everything) He likes to do, and there is none to force Him (to do or not to do this or that).
