نا نا أَبُو الْقَاسِمِ بْنُ مَنِيعٍ ، نا يَحْيَى بْنُ أَيُّوبَ ، نا عَبَّادُ بْنُ عَبَّادٍ ، نا هِشَامُ بْنُ حَسَّانَ ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ ، أَنَّ زَيْدَ بْنَ ثَابِتٍ سُئِلَ عَنِ الْعُمْرَةِ قَبْلَ الْحَجِّ ، فَقَالَ : " صَلاتَانِ لا يَضُرُّكَ بِأَيِّهِمَا بَدَأْتَ " .
It is narrated about Sayyiduna Zaid bin Thabit (may Allah be pleased with him): He was asked about performing ‘Umrah before Hajj, so he replied that these are two prayers; if you perform either of them first, there will be no harm.
