حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، قَالَ حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم وَمُعَاذُ بْنُ جَبَلٍ رَدِيفُهُ عَلَى الرَّحْلِ قَالَ " يَا مُعَاذُ " . قَالَ لَبَّيْكَ رَسُولَ اللَّهِ وَسَعْدَيْكَ . قَالَ " يَا مُعَاذُ " . قَالَ لَبَّيْكَ رَسُولَ اللَّهِ وَسَعْدَيْكَ . قَالَ " يَا مُعَاذُ " . قَالَ لَبَّيْكَ رَسُولَ اللَّهِ وَسَعْدَيْكَ . قَالَ " مَا مِنْ عَبْدٍ يَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ إِلاَّ حَرَّمَهُ اللَّهُ عَلَى النَّارِ " . قَالَ يَا رَسُولَ اللَّهِ أَفَلاَ أُخْبِرُ بِهَا النَّاسَ فَيَسْتَبْشِرُوا قَالَ " إِذًا يَتَّكِلُوا " فَأَخْبَرَ بِهَا مُعَاذٌ عِنْدَ مَوْتِهِ تَأَثُّمًا .
It is reported on the authority of Anas b. Malik that the Prophet of Allah (may peace and blessings be upon him) addressed Mu'adh b. Jabal as he was riding behind him to which he replied: At thy beck and call, and at thy pleasure, Messenger of Allah. He again called out: Mu'adh, to which he (again) replied: At thy beck and call, and at thy pleasure. He (the Holy Prophet) addressed him (again): Mu'adh, to which he replied: At thy beck and call, and at thy pleasure, Messenger of Allah. Upon this he (the Holy Prophet) observed: If anyone testifies (sincerely from his heart) that there is no god but Allah, and that Muhammad is His bondsman and His messenger, Allah immuned him from Hell. He (Mu'adh) said: Messenger of Allah, should I not then inform people of it, so that they may be of good cheer? He replied: Then they would trust in it alone. Mu'adh told about it at the time of his death, to avoid sinning. Translation Not Available
