عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ أَعْرَابِيٌّ: يَا رَسُولَ اللَّهِ! مَا الصُّورُ؟ قَالَ: ”قَرْنٌ يُنْفَخُ فِيهِ“
It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that a Bedouin asked: O Messenger of Allah! What is the Sur (Trumpet)? The Prophet (peace and blessings be upon him) said: It is a horn in which it will be blown.
