It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A servant is not granted the ability to do anything better than two rak'ahs that he prays. Indeed, goodness keeps showering upon the head of the servant as long as he is in his prayer. And the servants do not draw near to Allah, the Mighty and Majestic, with anything like that which came out from Him." Abu al-Nadr said: "Meaning the Qur'an."
