"A man asked Ibn Umar about touching the Black Stone and he said: 'I saw the Messenger of Allah touching it and kissing it.' The man said: 'What if it is too crowded and I am overwhelmed?' Ibn Umar, may Allah be pleased with him, said: 'Leave your "what if" in Yemen! I saw the Messenger of Allah touching it and kissing it.'" (Using translation from Nasāʾī 2946)
رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْتَلِمُهُ وَيُقَبِّلُهُ فَقَالَ رَجُلٌ أَرَأَيْتَ إِنْ زُحِمْتُ؟ فَقَالَ ابْنُ عُمَرَ اجْعَلْ أَرَأَيْتَ بِالْيَمَنِ!! رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْتَلِمُهُ وَيُقَبِّلُهُ
