[Machine] The Messenger of Allah ﷺ said: "Whoever swears by other than Allah has indeed disbelieved or associated partners with Him." And this is something that Saad bin Ubaydah did not hear from Ibn Umar.
رَسُولَ اللهِ ﷺ يَقُولُ مَنْ حَلَفَ بِغَيْرِ اللهِ فَقَدْ كَفَرَ أَوْ أَشْرَكَ وَهَذَا مِمَّا لَمْ يَسْمَعْهُ سَعْدُ بْنُ عُبَيْدَةَ مِنِ ابْنِ عُمَرَ
