لا إلهَ إلاّ اللّهُ وحدَهُ لا شريكَ لهُ، لهُ المُـلْكُ ولهُ الحَمْد، وهوَ على كلّ شَيءٍ قَدير، اللّهُـمَّ لا مانِعَ لِما أَعْطَـيْت، وَلا مُعْطِـيَ لِما مَنَـعْت، وَلا يَنْفَـعُ ذا الجَـدِّ مِنْـكَ الجَـد
La ilaha illal-lahu wahdahu la shareeka lah, lahul-mulku walahul-hamd, wahuwa AAala kulli shayin qadeer, allahumma la maniAAa lima aAAtayt, wala muAAtiya lima manaAAt, wala yanfaAAu thal-jaddi minkal-jad
Translation
None has the right to be worshipped except Allah, alone, without partner, to Him belongs all sovereignty and praise and He is over all things omnipotent. O Allah, none can prevent what You have willed to bestow and none can bestow what You have willed to prevent, and no wealth or majesty can benefit anyone, as from You is all wealth and majesty.
When to recite
Recited after salam at the end of prayer.
