Hadith #1

1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ رَفَعَهُ قَالَ سَمِعَ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) رَجُلا يَقُولُ أَنَا بَرِي‏ءٌ مِنْ دِينِ مُحَمَّدٍ فَقَالَ لَهُ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) وَيْلَكَ إِذَا بَرِئْتَ مِنْ دِينِ مُحَمَّدٍ فَعَلَى دِينِ مَنْ تَكُونُ قَالَ فَمَا كَلَّمَهُ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) حَتَّى مَاتَ.

1. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from in a marfu‘ manner who has narrated the following: “The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, once heard a man saying, T disown the religion of Muhammad.’ The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, then asked saying, ‘Woe is upon you, if you are not a follower of the religion of Muhammad, then whose religion do you follow?’ He (the Imam) has said that as soon as the words of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, were complete, he (the man) dropped dead.’”
