Argumentation lifts blessings; The day of Laylat al-Qadr was made to be forgotten due to some believers that were quarreling
The Messenger of Allah ﷺ went out to inform the people about the ˹date of the˺ Night of Decree (Laylat 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 Qadr, but as so and so have quarrelled, and its knowledge has been taken away (i.e. I have made to forgot it) and maybe it was better for you. Now look for it in the seventh, the sixth and the fifth ˹of the last ten nights of the month of Ramaḍān)."
أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ يُخْبِرُ بِلَيْلَةِ الْقَدْرِ فَتَلاَحَى رَجُلاَنِ مِنَ الْمُسْلِمِينَ فَقَالَ: «إِنِّي خَرَجْتُ لأُخْبِرَكُمْ بِلَيْلَةِ الْقَدْرِ وَإِنَّهُ تَلاَحَى فُلاَنٌ وَفُلاَنٌ فَرُفِعَتْ وَعَسَى أَنْ يَكُونَ خَيْرًا لَكُمُ الْتَمِسُوهَا فِي السَّبْعِ وَالتِّسْعِ وَالْخَمْسِ۔»
