Hadith 2:241
Narrated Khalid bin Ma'dan (RA):
Surat al-Hajj has been distinguished by two prostrations. [Abu Dawud reported it among al-Marasil (a broken chain after the Tabi'i)].
وَعَنْ خَالِدِ بْنِ مَعْدَانَ - رضى الله عنه - قَالَ : { فُضِّلَتْ سُورَةُ اَلْحَجِّ بِسَجْدَتَيْنِ } . رَوَاهُ أَبُو دَاوُدَ فِي " اَلْمَرَاسِيلِ "
