Abu Huraira reported that God's Messenger said to Bilal at the dawn prayer, “Tell me, Bilal, of the action you have done since becoming a Muslim which is most calculated to cause hope in you, for I heard the sound of your sandals in front of me in paradise.” He replied, “I have done no action more calculated, in my opinion to cause hope than that I have never performed ablution at any hour of the night or day without immediately praying what was ordained for me to pray.”
I asked Ibn ‘Umar whether he prayed in the forenoon and he said he did not. I asked whether ‘Umar did and he said he did not. I asked whether Abu Bakr did and he said he did not. I asked whether the Prophet did and he said, “I don’t think so.”
God’s Messenger used to teach us how to ask God’s guidance about matters just as he used to teach as a sura of the Qur’an, saying: When any of you intends to do something he should pray two rak'as which are not compulsory, then say, “O God, I ask Thy guidance by Thy knowledge, I ask Thee for power by Thy power, and I ask Thee out of Thy great abundance, for Thou hast power and I have none, Thou knowest and I did not, and Thou art the One who is aware of the unseen. O God, if Thou knowest that this matter is good for me regarding my religion, my livelihood, and my future wellbeing (or he said, “my affairs in this world and the next”), ordain it for me and make it easy for me, then bless me in it. But if Thou knowest that this matter is bad for me regarding my religion, my livelihood, and my future wellbeing (or he said, “my affairs in this world and the next”), turn it away from me, turn me away from it, ordain good for me wherever it is, then make me pleased with it.” He said that he should name what he required.
God’s Messenger used to pray in the forenoon so often that we felt he would never stop doing so; then he would leave off doing so for so long that we felt he would never resume prayer at that time.
