When the Messenger of Allah ﷺ finished the prayer and pronounced salutation he uttered (this supplication):" There is no god but Allah. He is alone, Who has no partner. To Him belongs the sovereignty and to Him praise is due and He is Potent over every. thing. O Allah! no one can withhold what Thou givest, or give what Thou withholdest, and the riches cannot avail a wealthy person with Thee." (Using translation from Muslim 593a)
أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ دُبُرَ الصَّلَاةِ إِذَا سَلَّمَ «لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ اللهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ»
