وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ ۚ وَلَوْلَآ أَجَلٌۭ مُّسَمًّۭى لَّجَآءَهُمُ ٱلْعَذَابُ وَلَيَأْتِيَنَّهُم بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ
They bid thee hasten on the doom (of Allah). And if a term had not been appointed, the doom would assuredly have come unto them (ere now). And verily it will come upon them suddenly when they perceive not.
Surah Al-Ankaboot(29:53)
Sahih al-Bukhari
Call to Prayers (Adhaan)
Chapter: The shortening of the Qiyam (standing) by the Imam[in Salat (prayer)] but performing the bowings and the prostrations perfectly
Narrated Abu Mas`ud:
A man came and said, "O Allah's Messenger (ﷺ)! By Allah, I keep away from the morning prayer only because So and so prolongs the prayer when he leads us in it." The narrator said, "I never saw Allah's Apostle more furious in giving advice than he was at that time. He then said, "Some of you make people dislike good deeds (the prayer). So whoever among you leads the people in prayer should shorten it because among them are the weak, the old and the needy."
