Abu Hurairah (may Allah be pleased with him) narrates that the Prophet of Allah (peace be upon him) said to Bilal (may Allah be pleased with him) at the time of Fajr prayer: "O Bilal, tell me about the deed you have done after embracing Islam from which you hope for the greatest benefit." Indeed, I heard the sound of your footsteps ahead of me in Paradise last night." He replied, "O Messenger of Allah, in my view, after embracing Islam, I have not done any deed from which I hope for more benefit, reward, and recompense than this: that whenever I performed a complete ablution, whether during the night or day, I offered as many voluntary prayers with that ablution for the sake of my Lord's pleasure as were destined for me to offer."
