Abu Huraira reported God’s messenger as saying, “If anyone finds pleasure in receiving an answer from God in times of difficulty, he should make many supplications when times are easy.”
Tirmidhi transmitted it, saying this is a gharib tradition.
Ibn ‘Umar reported God's messenger as saying, “If the gate of supplication is opened for any of you, the gates of mercy will be opened for him, and God is not asked for anything He likes so much as to be asked for security.”
He reported God’s messenger as saying, “Supplicate God when you are assured of being answered, and know that God does not answer a supplication which comes from a careless and inattentive heart.”
Tirmidhi transmitted it, saying this is a gharib tradition.
