“Whoever says it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise”
[Sahih al-Bukhari 8, 75 no318]
“And be patient, [O Muhammad], for the decision of your Lord, for indeed, you are in Our eyes. And exalt [Allah] with praise of your Lord when you arise.” [52:48]
