Musnad Ahmad 254
As-Subayy bin Ma`bad was a man from (the tribe of) Banu Taghlib, He said:
I was a Christian, then I became Muslim. I thought long and hard, and decided to enter ihram for Hajj and `Umrah. I passed by Salman bin Rabee`ah and Zaid bin Soohan in al-`Udhaib, and one of them said: Are you doing both of them? His companion said to him. Let him be; he is more misguided than his came! He [as-Subayy] said: It was as if my camel was on my shoulders [i.e., because he was so upset by their words]. I went to ‘Umar and told him about that. ‘Umar said to me: They did not say anything (that matters); you have been guided to the Sunnah of your Prophet (ﷺ).
حَدَّثَنَا يَحْيَى، عَنِ الْأَعْمَشِ، حَدَّثَنَا شَقِيقٌ، حَدَّثَنِي الصُّبَيُّ بْنُ مَعْبَدٍ، وَكَانَ، رَجُلًا مِنْ بَنِي تَغْلِبَ قَالَ كُنْتُ نَصْرَانِيًّا فَأَسْلَمْتُ فَاجْتَهَدْتُ فَلَمْ آلُ فَأَهْلَلْتُ بِحَجَّةٍ وَعُمْرَةٍ فَمَرَرْتُ بِالْعُذَيْبِ عَلَى سَلْمَانَ بْنِ رَبِيعَةَ وَزَيْدِ بْنِ صُوحَانَ فَقَالَ أَحَدُهُمَا أَبِهِمَا جَمِيعًا فَقَالَ لَهُ صَاحِبُهُ دَعْهُ فَلَهُوَ أَضَلُّ مِنْ بَعِيرِهِ قَالَ فَكَأَنَّمَا بَعِيرِي عَلَى عُنُقِي فَأَتَيْتُ عُمَرَ رَضِيَ اللَّهُ عَنْهُ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ لِي عُمَرُ إِنَّهُمَا لَمْ يَقُولَا شَيْئًا هُدِيتَ لِسُنَّةِ نَبِيِّكَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ‏.‏
