Anas said that God’s messenger performed the 'umra four times, each of them Dhul Qa'da except the one which was combined with his hajja, one from al-Hudaibiya in Dhul Qa'da, one in the following year in Dhul Qa'da, one from al-Ji'rana where he divided the spoils of Hunain (The battle in which the Prophet defeated Hawazin after the conquest of Mecca in 8 A.H) in Dhul Qa'da, and one along with his hajja. Bukhari and Muslim.
وَعَنْ أَنَسٍ قَالَ: اعْتَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَرْبَعٌ عُمَرٍ كُلُّهُنَّ فِي ذِي الْقَعْدَةِ إِلَّا الَّتِي كَانَتْ مَعَ حَجَّتِهِ: عُمْرَةً مِنَ الْحُدَيْبِيَةِ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مِنَ الْعَامِ الْمُقْبِلِ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مِنَ الْجِعْرَانَةِ حَيْثُ قَسَّمَ غَنَائِمَ حُنَيْنٍ فِي ذِي الْقَعْدَةِ وَعُمْرَةً مَعَ حَجَّتِهِ "
