Hadith 13762942 - وَ سَأَلَهُ عَبْدُ اَللَّهِ بْنُ سِنَانٍ : عَنِ اَلْمَمْلُوكِ يَكُونُ فِي اَلظَّهْرِ يَرْعَى وَ هُوَ يَرْضَى أَنْ يَعْتَمِرَ ثُمَّ يَخْرُجَ فَقَالَ «إِنْ كَانَ اِعْتَمَرَ فِي ذِي اَلْقَعْدَةِ فَحَسَنٌ وَ إِنْ كَانَ فِي ذِي اَلْحِجَّةِ فَلاَ يَصْلُحُ إِلاَّ اَلْحَجُّ ».
Hadith.2942 - Abdullah ibn Sinan asked Imam (as) about a servant who is out grazing animals and agrees to perform Umrah and then leave.
Imam (as) said: "If he performed Umrah in Dhu al-Qa'dah, it is good. But if it is in Dhu al-Hijjah, then it is not suitable except for Hajj."
