Warning the Disbelievers of the imminent Torment; commanding the Prophet to pray and have Patience

Allah the Exalted asks, `how many We have destroyed before these denying disbelievers'

مِّن قَرْنٍ هُمْ أَشَدُّ مِنْهُم بَطْشاً

وَأَدْبَارَ‌ السُّجُودِ (...and at the ends of prostration.... 50:40) Mujahid (رح) interprets sujud in this verse to refer to the five obligatory prayers, and the phrase "at the ends of the prostrations", according to him, refers to all those tasbihat which authentic ahadith encourage us to recite after every prayer. Sayyidna Abu Hurairah ؓ reports that the Holy Prophet ﷺ said: "Whosoever recites after every obligatory prayer 33 times subhanallah (سُبحَانَ اللہ), 33 times al-hamdulillah (اَلحَمدُ للہ) and 33 times allahu 'akbar (اللہُ اَکبَر), and once:

لَا اِلٰہَ ِالّا اللہُ وَحدَہُ ، لَا شَرِیکَ لَہُ ، لَہُ المُلکُ وَ لَہُ الحَمدُ وھُوَ علیٰ کُلِّ شیٔ قَدِیر
