أَوَلَا يَرَوْنَ أَنَّهُمْ يُفْتَنُونَ فِى كُلِّ عَامٍۢ مَّرَّةً أَوْ مَرَّتَيْنِ ثُمَّ لَا يَتُوبُونَ وَلَا هُمْ يَذَّكَّرُونَ
See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they heed.

Belief
Chapter: (What is said regarding) the fear of a believer that his good deeds may be annulled (lost) without his knowledge
Narrated 'Ubada bin As-Samit:
"Allah's Messenger (ﷺ) went out to inform the people about the (date of the) night of decree (Al-Qadr) but there happened a quarrel between two Muslim men. The Prophet (ﷺ) said, "I came out to inform you about (the date of) the night of Al-Qadr, but as so and so and so and so quarrelled, its knowledge was taken away (I forgot it) and maybe it was better for you. Now look for it in the 7th, the 9th and the 5th (of the last 10 nights of the month of Ramadan)."
