Hazrat Abdul Aziz Abi Rawad (may Allah have mercy on him) says that when some jest and laughter began to appear in the habits of the Companions of the Prophet, Allah the Exalted revealed this verse: { أَلَمْ یَأْنِ لِلَّذِینَ آمَنُوا أَنْ تَخْشَعَ قُلُوبُہُمْ لِذِکْرِ اللہِ } till the end of the verse. "Has the time not come for those who have believed that their hearts should become humbly submissive at the remembrance of Allah?"
