Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 14

وَعَنِ الْبَرَاءِ بْنِ عَازِبٍ قَالَ: اعْتَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي ذِي الْقَعْدَةِ قَبْلَ أَنْ يَحُجَّ مَرَّتَيْنِ “. رَوَاهُ الْبُخَارِيُّ

Al-Bara’ b. ‘Azib said that God’s messenger performed the ‘umra twice in Dhul Qa’da before performing the hajj . Bukhari transmitted it.
