عَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ”إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يُسَلِّمَ الرَّجُلُ عَلَى الرَّجُلِ لَا يُسَلِّمُ عَلَيْهِ إِلَّا لِلْمَعْرِفَةِ“
It is narrated from Sayyiduna Abdullah bin Masood (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: This is also among the signs of the Hour, that a man will greet another only because of acquaintance and familiarity.
