صحيح البخاري Sahih Bukhari كتاب الاعتصام بالكتاب والسنة The Book of Holding Fast To The Qur’An and The Sunna
بَابُ مَنْ رَأَى تَرْكَ النَّكِيرِ مِنَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حُجَّةً لاَ مِنْ غَيْرِ الرَّسُولِ:

(23) Chapter. Whoever thinks that if the Prophet (p.b.u.h.) did not disapprove of something (said or done in his presence), his silence indicated that it was permissible, but if another person faced a similar situation, his silence should not be taken as a sign of his agreement.

حَدَّثَنَا حَمَّادُ بْنُ حُمَيْدٍ ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا شُعْبَةُ ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ ، قَالَ : " رَأَيْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يَحْلِفُ بِاللَّهِ أَنَّ ابْنَ الصَّائِدِ الدَّجَّالُ ، قُلْتُ : تَحْلِفُ بِاللَّهِ ؟ ، قَالَ : إِنِّي سَمِعْتُ عُمَرَ يَحْلِفُ عَلَى ذَلِكَ عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمْ يُنْكِرْهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " .
Narrated Muhammad bin Al-Munkadir: I saw Jabir bin `Abdullah swearing by Allah that Ibn Sayyad was the Dajjal. I said to Jabir, "How can you swear by Allah?" Jabir said, "I have heard `Umar swearing by Allah regarding this matter in the presence of the Prophet and the Prophet did not disapprove of it."
