عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ قَالَ خَرَجْتُ مَعَ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا نَتَلَقَّى الْحَاجَّ فَنُسَلِّمُ عَلَيْهِمْ قَبْلَ أَنْ يَتَدَنَّسُوا
Habib bin Abi Thabit says: I went out with Sayyiduna Ibn Umar (may Allah be pleased with them both) to meet those returning from the performance of Hajj; we would greet them with salam before they became soiled due to sins.
