Prophet (salallaahu ‘alaihi wassallam) said: “Whoever says when he enters the morning: Radeetu billaahi Rabban, wa bil-Islaami Deenan, wa bi-Muhammadin nabiyyan, (I am pleased with Allaah as the Lord, and with Islaam as a Religion, and with Muhammad as a Prophet), then I am the guarantor that I will take him by his hand until I enter him into Jannah.” As-Sahīhah, no. 2686.

‘Abdullaah ibn ‘Amr ibn Al-‘Aas heard the Prophet (sallallaahu ‘alayhe wa sallam) saying:
“It will be said to the companion of the Qur’aan: Read and elevate(up through the levels of the Paradise) and beautify your voice as you used to do when you were in the dunyaa! For verily, your position in the Paradise will be at the last verse you recite!”

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “Everyone among you will be deemed to be occupied in Salat (prayer) constantly so long as Salat (the prayer) detains him (from worldly concerns), and nothing prevents him from returning to his family but Salat.”
[Al-Bukhari and Muslim].
Commentary: This Hadith tells us the merits of waiting for Salat. As long as a person sits in mosque waiting for Salat, all his time is reckoned as being in the state of Salat and so eligible for the same reward.
Anas (May Allah be pleased with him) reported: Once the Messenger of Allah (sallallaahu ’alayhi wa sallam) delayed the night prayer (`Isha’) till midnight. He (sallallaahu ’alayhi wa sallam) turned to us after Salat (prayer) and said, “The people slept after performing their Salat, but you who waited, will be accounted as engaged in Salat throughout the period of your waiting.”
