Mishkat al-Masabih, 2536

Abu Huraira reported the Prophet (ﷺ) as saying, “Those who perform the <i>hajj</i> and those who perform the <i>'umra</i> are people who have come to visit God. If they supplicate Him He will respond to them, and if they ask Him for forgiveness He will forgive them.” Ibn Majah transmitted it.

وَعَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ: «الْحَاجُّ وَالْعُمَّارُ وَفْدُ اللَّهِ إِنْ دَعَوْهُ أجابَهمْ وإِنِ استَغفروهُ غَفرَ لهمْ» . رَوَاهُ ابْن مَاجَه
