عن ابن عَبَّاسٍ رضي اللَّهُ عنهما، قال: ( دَخَلَ رسولُ الله صَلّى اللهُ عليهِ وسلَّم على عمرَ ومعه أناس من أصحابه، فقال: « أَمُؤْمِنُونَ أَنْتُم ؟» فسكتوا – ثلاث مرات- فقال عمر في آخرهم: نعم، نؤمنُ على ما أتيتنا به، ونحمدُ اللهَ في الرَّخَاءِ، ونصبر على البلاء، ونؤمن بالقضاء، فقال رسولُ الله صَلّى اللهُ عليهِ وسلَّم: « مُؤْمِنُونَ وَرَبِّ الكَعْبَةِ»). رواه الطبراني والهيثمي.
Narrated Ibn Abbas -may Allah be pleased with them- said: “The Messenger of Allah -prayer and peace be upon him- once visited Omar and few of his companions were with the latter, so the Messenger of Allah -prayer and peace be upon him- asked: ‘Are you Mu’minoon (Faithful believers)?’ They kept silent. He asked three times so Omar replied after the last time: ‘Yes, we believe in the message you were sent with, thank (Allah) during ease, bear patiently during hardship, and believe and accept pre-destiny.’ So the Messenger of Allah -prayer and peace be upon him- said: ‘True believers (Mu’minoon) by the Lord of Ka’bah.’ ” Related by Al-Tabarani, and Al-Heithami.
The Trial of the Fire
Narrated Sherhabeel Ibn Muslim said: “When Al-Aswad Ibn Qais Al-‘Ansi, the apostate, the imposter, claimed to be a prophet falsely in Yemen, he sent for Abu Muslim Al-Khawlani. When Abu Muslim was brought to him, Al-Aswad, the imposter, asked him: ‘Do you testify that I am a messenger of Allah?’ Abu Muslim replied: ‘I can’t hear what you say.’ He asked Abu Muslim: ‘Do you testify that Muhammad is the Messenger of Allah?’ Abu Muslim replied: ‘Yes, I do.’ Al-Aswad repeated the questions, and Abu Muslim replied the same. So Al-Aswad asked his men to make a great fire and throw Abu Muslim into it. But the great fire did not harm Abu Muslim (by the will of God). It was said to Al-Aswad: ‘Send him away, or he will drive away your followers.’ So he asked Abu Muslim to leave.
Abu Muslim went to visit Al-Medinah, while Prophet Muhammad -prayer and peace be upon him- had passed away, and Abu-Bakr -may Allah be pleased with him- was elected as caliph. Once in Al-Medinah, Abu Muslim left his mount at the door of the Great Mosque of the Prophet, then went inside the mosque and started praying behind a pillar.
Omar saw him, so went to him and asked: ‘Where is the man (you) from?’ Abu Muslim replied: ‘From Yemen.’ Omar asked: ‘Then maybe you are the one whom the imposter threw into the fire?’ Abu Muslim hedged: ‘That was Abdul-Allah Ibn Thowb [Abu Muslim’s real name].’ Omar said: ‘I beseech you by Allah, are you that person?’ Abu Muslim replied: ‘Yes, that is me, by Allah.’ So Omar embraced him, and cried.
Omar then took Abu Muslim to the Caliph Abu-Bakr, and seated him between himself and Abu Bakr -may Allah be pleased with them, and then said: ‘Praise be to Allah Who did not take my soul until I had seen among the nation of Prophet Muhammad -prayer and peace be upon him- a person who was treated the same as Prophet Ibrahim, the close friend of the Most Merciful (Khaleel Al-Rahman).’ ” Related by Abu Nu’eim in Hilyatul Awliya‘ (The Ornament of the Saints).
