قَالَ أَبُو عَبْدِ اللَّهِ ع السَّنَةُ اثْنَا عَشَرَ شَهْراً يُعْتَمَرُ لِكُلِّ شَهْرٍ عُمْرَةٌ[4].
Hadith.2964 - Ishaq ibn Ammar narrated that Abu Abdullah (as) said: "The year has twelve months, and an Umrah can be performed in each month."
فَقُلْتُ لَهُ أَ يَكُونُ أَقَلَّ مِنْ ذَلِكَ قَالَ لِكُلِّ عَشَرَةِ أَيَّامٍ عُمْرَةٌ[6].
"There is an Umrah for every month." I asked him: "Can it be less than that?" Imam (as) said: "There is an Umrah for every ten days."
حَسَنٌ[2].
I asked him about performing Umrah after Hajj in Dhu al-Hijjah. Imam (as) said: "It is good."
