There are several Ahadith that mention the rewards of admitting that the return is to Allah by saying:

﴿ط¥ظگظ†ظ‘ظژط§ ظ„ظگظ„ظ‘ظژظ‡ظگ ظˆظژط¥ظگظ†ظ‘ظژظ€ط¢ ط¥ظگظ„ظژظٹظ’ظ‡ظگ ط±ظژط¬ظگط¹ظˆظ†ظژ﴾

("Truly, to Allah we belong and truly, to Him we shall return.'') when afflictions strike. For instance, Imam Ahmad reported that Umm Salamah narrated: Once, Abu Salamah came back after he was with Allah's Messenger and said: I heard Allah's Messenger recite a statement that made me delighted. He said:

آ«ظ„ظژط§ ظٹظڈطµظگظٹط¨ظڈ ط£ظژط­ظژط¯ظ‹ط§ ظ…ظگظ†ظژ ط§ظ„ظ’ظ…ظڈط³ظ’ظ„ظگظ…ظگظٹظ†ظژ ظ…ظڈطµظگظٹط¨ظژط©ظŒ ظپظژظٹظژط³ظ’طھظژط±ظ’ط¬ظگط¹ظڈ ط¹ظگظ†ظ’ط¯ظژ ظ…ظڈطµظگظٹط¨ظژطھظگظ‡ظگ ط«ظڈظ…ظ‘ظژ ظٹظ‚ظڈظˆظ„ظڈ: ط§ظ„ظ„ظ‘ظژظ‡ظڈظ…ظ‘ظژ ط£ظ’ط¬ظڈط±ظ’ظ†ظگظٹ ظپظگظٹ ظ…ظڈطµظگظٹط¨ظژطھظگظٹ ظˆط£ظژط®ظ’ظ„ظگظپظ’ ظ„ظگظٹ ط®ظژظٹظ’ط±ظ‹ط§ ظ…ظگظ†ظ’ظ‡ظژط§طŒ ط¥ظگظ„ظ‘ظژط§ ظپظژط¹ظژظ„ظژ ط°ظ„ظگظƒظژ ط¨ظگظ‡آ»

(No Muslim is struck with an affliction and then says Istirja` when the affliction strikes, and then says: `O Allah! Reward me for my loss and give me what is better than it,' but Allah will do just that.) Umm Salamah said: So I memorized these words. When Abu Salamah died I said Istirja` and said: "O Allah! Compensate me for my loss and give me what is better than it.'' I then thought about it and said, "Who is better than Abu Salamah'' When my `Iddah (the period of time before the widow or divorced woman can remarry) finished, Allah's Messenger asked for permission to see me while I was dyeing a skin that I had. I washed my hands, gave him permission to enter and handed him a pillow, and he sat on it. He then asked me for marriage and when he finished his speech, I said, "O Messenger of Allah! It is not because I do not want you, but I am very jealous and I fear that you might experience some wrong mannerism from me for which Allah would punish me. I am old and have children.'' He said:

(As for the jealousy that you mentioned, Allah the Exalted will remove it from you. As for your being old as you mentioned, I have suffered what you have suffered. And for your having children, they are my children too.) She said, "I have surrendered to Allah's Messenger.'' Allah's Messenger married her and Umm Salamah said later, "Allah compensated me with who is better than Abu Salamah: Allah's Messenger .'' Muslim reported a shorter version of this Hadith.

(158. Verily, As-Safa and Al-Marwah are of the symbols of Allah. So it is not a sin on him who performs Hajj or `Umrah (pilgrimage) of the House to perform Tawaf between them. And whoever does good voluntarily, then verily, Allah is All-Recognizer, All-Knower).
