Hadith 8:695
Abu Bakr narrated to us, he said: Yahya ibn Adam narrated to us, from Ya’la ibn al-Harith, he said: We heard Abu Ishaq, and he was asked about the ‘Umrah of Ramadan, so he said: I reached the companions of ‘Abdullah, and they did not consider the ‘Umrah of Rajab equal to it, then they would proceed to the Hajj.
حدثنا أبو بكر قال حدثنا يحيى بن آدم عن يعلى بن الحارث قال سمعنا أبا إسحاق وسئل عن عمرة رمضان فقال أدركت أصحاب عبد الله لا يعدلون بعمرة رجب ثم يستقبلون الحج
