"I said: 'O Messenger of Allah! Surah Al-Hajj has been esteemed by two prostrations?' He said: 'Yes, and whoever does not prostrate for them, he should not recite them.'"  

قُلْتُ يَا رَسُولَ اللَّهِ فُضِّلَتْ سُورَةُ الْحَجِّ بِأَنَّ فِيهَا سَجْدَتَيْنِ قَالَ نَعَمْ وَمَنْ لَمْ يَسْجُدْهُمَا فَلاَ يَقْرَأْهُمَا
