Hadith on Ramadan: Knowledge of Laylat al-Qadr removed by insults

Ubaida ibn al-Samit reported: The Messenger of Allah, peace and blessings be upon him, came out to inform people about the Night of Decree in Ramadan, but two Muslim men were insulting each other. The Prophet said, “Verily, I have come out to tell you about the Night of Decree, but two men were insulting each other. Thus, its knowledge was removed and perhaps it is better for you. Look for it during the seventh, ninth, or fifth night of the last ten nights.

عن عبادة بن الصامت أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ يُخْبِرُ بِلَيْلَةِ الْقَدْرِ فَتَلَاحَى رَجُلَانِ مِنْ الْمُسْلِمِينَ فَقَالَ إِنِّي خَرَجْتُ لِأُخْبِرَكُمْ بِلَيْلَةِ الْقَدْرِ وَإِنَّهُ تَلَاحَى فُلَانٌ وَفُلَانٌ فَرُفِعَتْ وَعَسَى أَنْ يَكُونَ خَيْرًا لَكُمْ الْتَمِسُوهَا فِي السَّبْعِ وَالتِّسْعِ وَالْخَمْسِ
