Hum se Muhammad bin Husain bin Ibrahim ne bayan kiya, unhon ne kaha hum se Ubaidullah bin Musa Kufi ne bayan kiya, unhon ne kaha hamain ko Shayban Nahwi ne khabar di, unhon ne Firas bin Yahya se, unhon ne Aamir Shabi se, unhon ne Abdullah bin Amr bin al-Aas razi Allahu anhuma ne, unhon ne kaha ke ek ganwar (naam na-maloom) Nabi Karim salla Allahu alaihi wasallam ke paas aaya kehne laga: ya Rasool Allah! Bade bade gunah kaun se hain? Aap salla Allahu alaihi wasallam ne farmaya ”Allah ke saath shirk karna.“ Is ne poochha phir kaun sa gunah? Aap ne farmaya ”maan baap ko satana.“ Poochha: phir kaun sa gunah? Aap ne farmaya ” «ghamoos» qasam khana.“ Abdullah bin Amr razi Allahu anhuma ne kaha main ne arz kiya: ya Rasool Allah! «ghamoos» qasam kiya hai? Aap salla Allahu alaihi wasallam ne farmaya ”jaan boojh kar kisi Musalman ka maal maar lene ke liye jhooti qasam khana.“
