On the night before Fatima alzahraa’s (as) wedding her father got her a lovely dress. She was looking at the dress and admiring it, until someone knocked on the door. A person said “O family of the prophet! I am someone who is poor and has nothing and i came to the house of mercy. I beg of you to give me something”
Lady Fatima (as) heard this and thought to her self “i will give the other dress that i have” but then she remembered the verse in the Quran that said “you will never achieve righteousness until you are willing to give away that which you love the most!” She loved her new dress and she went to the person at the door and said “ here is my dress. It is new. Go and sell it and inshallah it will bring you a good income”
On her wedding day she wore a patched-up dress.
Just then the prophet came to her and said “hurry go get ready”. She said “why?” He said, “jibra'il had just came to me with a dress which allah has honored from jannah” This shows that if you give your sake to Allah, you think he wont give it back?

رسولُ اللهِ‏ِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): يا أبا ذَرٍّ ، إنّ اللّه‏َ تعالى يُعطِيكَ مادُمتَ جالِساً في المَسجِدِ بِكُلِّ نَفَسٍ تَنَفَّستَ دَرَجةً في الجَنَّةِ ، وتُصَلِّي علَيكَ الملائكةُ ، وتُكتَبُ لَكَ بِكُلِّ نَفَسٍ تَنَفَّستَ فيهِ عَشرُ حَسَناتٍ ، وتُمحى عنكَ عَشرُ سَيّئاتٍ.

5– The Prophet (SAWA) said, ‘O AbU Dharr, verily for as long as you remain seated in the mosque Allah, most High, will grant you an extra level in Paradise for every breath you take, the angels send salutations on you, and ten good deeds are recorded and ten evil deeds wiped away for every breath you take therein.’[Bihar al-Anwar, v. 77, p. 85, no. 3]
