خِلاَفَةُ النُّبُوَّةِ ثَلاَثُونَ سَنَةً ثُمَّ يُؤْتِي اللَّهُ الْمُلْكَ مَنْ يَشَاءُ - أَوْ مُلْكَهُ مَنْ يَشَاءُ - "
Safinah reported the Messenger of Allah (ﷺ) as saying: The caliphate of Prophecy will last thirty years; then Allah will give the Kingdom to whom he wishes; or his kingdom to whom he wishes.
