عن عمر بن الخطاب رضي الله عنه قال: بَيْنَمَا نَحْنُ عِنْدَ رَسُولِ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ إِذْ طَلَعَ عَلَيْنَا رَجُلٌ شَدِيدُ بَيَاضِ الثِّيَابِ، شَدِيدُ سَوَادِ الشَّعَرِ، لَا يُرَى عَلَيْهِ أَثَرُ السَّفَرِ، وَلَا يَعْرِفُهُ مِنَّا أَحَدٌ، حَتَّى جَلَسَ إِلَى النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، فَأَسْنَدَ رُكْبَتَيْهِ إِلَى رُكْبَتَيْهِ، وَوَضَعَ كَفَّيْهِ عَلَى فَخِذَيْهِ، وَقَالَ: يَا مُحَمَّدُ، أَخْبِرْنِي عَنِ الْإِسْلَامِ، فَقَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «الْإِسْلَامُ أَنْ تَشْهَدَ أَنْ لَا إِلَهَ إِلَّا اللهُ، وَأَنَّ مُحَمَّدًا رَسُولُ اللهِ، وَتُقِيمَ الصَّلَاةَ، وَتُؤْتِيَ الزَّكَاةَ، وَتَصُومَ رَمَضَانَ، وَتَحُجَّ الْبَيْتَ إِنِ اسْتَطَعْتَ إِلَيْهِ سَبِيلًا» قَالَ: صَدَقْتَ، قَالَ: فَعَجِبْنَا لَهُ، يَسْأَلُهُ وَيُصَدِّقُهُ، قَالَ: فَأَخْبِرْنِي عَنِ الْإِيمَانِ، قَالَ: «أَنْ تُؤْمِنَ بِاللهِ، وَمَلَائِكَتِهِ، وَكُتُبِهِ، وَرُسُلِهِ، وَالْيَوْمِ الْآخِرِ، وَتُؤْمِنَ بِالْقَدَرِ خَيْرِهِ وَشَرِّهِ» قَالَ: صَدَقْتَ، قَالَ: فَأَخْبِرْنِي عَنِ الْإِحْسَانِ، قَالَ: «أَنْ تَعْبُدَ اللهَ كَأَنَّكَ تَرَاهُ، فَإِنْ لَمْ تَكُنْ تَرَاهُ فَإِنَّهُ يَرَاكَ» قَالَ: فَأَخْبِرْنِي عَنِ السَّاعَةِ، قَالَ: «مَا الْمَسْؤُولُ عَنْهَا بِأَعْلَمَ مِنَ السَّائِلِ» قَالَ: فَأَخْبِرْنِي عَنْ أَمَارَتِهَا، قَالَ: «أَنْ تَلِدَ الْأَمَةُ رَبَّتَهَا، وَأَنْ تَرَى الْحُفَاةَ الْعُرَاةَ الْعَالَةَ رِعَاءَ الشَّاءِ يَتَطَاوَلُونَ فِي الْبُنْيَانِ» قَالَ: ثُمَّ انْطَلَقَ، فَلَبِثْتُ مَلِيًّا ثُمَّ قَالَ لِي: «يَا عُمَرُ، أَتَدْرِي مَنِ السَّائِلُ؟» قُلْتُ: اللهُ وَرَسُولُهُ أَعْلَمُ، قَالَ: «فَإِنَّهُ جِبْرِيلُ، أَتَاكُمْ يُعَلِّمُكُمْ دِينَكُمْ».
Imepokewa Kutoka kwa Omar bin Khattwab -Radhi za Allah ziwe juu yake- amesema: Siku moja tukiwa tumekaa kwa Mtume -Rehema na amani ziwe juu yake- ghafla akatokea mtu mwenye nguo nyeupe mno, mwenye nywele nyeusi mno, haonekani kuwa na athari yoyote ya safari, na hakuna yeyote amjuaye miongoni mwetu, akaja mpaka akakaa kwa Mtume -Rehema na amani ziwe juu yake-, akakunja magoti yake kwa kuyaunganisha na magoti yake mtume (Mithili ya tahiyatu) Na akaweka viganja vyake juu ya mapaja yake, na akasema: Ewe Muhammadi, nieleze kuhusu Uislamu, akasema Mtume -Rehema na amani ziwe juu yake-: "Uislamu ni ushuhudie kuwa hapana Mola apasaye kuabudiwa kwa haki isipokuwa Mwenyezi Mungu, nakuwa Muhammadi ni Mjumbe wa Mwenyezi Mungu, na usimamishe sala, na utoe zake, na ufunge Ramadhani, na uhiji katika nyumba tukufu ikiwa utapata uwezo wa kuifikia" Akasema: Sadakta! (Umesema kweli), Anasema: Tukamshangaa: Anamuuliza na anamsadikisha! Akasema: Nieleze kuhusu imani. Akasema: "Nikuwa, umuamini Mwenyezi Mungu, na Malaika wake, na vitabu vyake, na Mitume wake, na siku ya mwisho, na uamini Kadari kheri yake na shari yake" Akasema: Sadakta! (Umesema kweli), akasema: Nieleza kuhusu Ihisani, akasema: "Ni umuabudu Mwenyezi Mungu kana kwamba unamuona, na ikiwa wewe humuoni basi yeye anakuona" Akasema: Nieleze kuhusu Kiyama, akasema: "Muulizwaji si mjuzi sana kama muulizaji" Akasema: Hebu nieleze kuhusu alama zake, akasema: "Ni mjakazi kuzaa bosi wake, na ukiwaona watembea peku, watembea uchi, tena masikini wachunga mbuzi, wakishindana kujenga majengo marefu." (Omar) Akasema: Kisha akaondoka, nikakaa muda mrefu kidogo, kisha Mtume akasema kuniambia: "Ewe Omari, hivi unamjua ni nani muulizaji?" Nikasema: Allah na Mtume wake ndio wajuzi zaidi, akasema: "Huyo ni Jibrili alikuja kukufundisheni dini yenu."
‘Umar ibn al-Khattāb (may Allah be pleased with him) reported: One day, we were sitting with the Messenger of Allah (may Allah's peace and blessings be upon him) when there appeared before us a man dressed in extremely white clothes and had very black hair. No traces of travel were visible on him, and none of us knew him. He came in and sat down opposite the Prophet (may Allah's peace and blessings be upon him), rested his knees against his, and placed the palms of his hands on his (the Prophet's) thighs. He said: "O Muhammad, tell me about Islam." The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Islam is to testify that there is no god but Allah and that Muhammad is the Messenger of Allah, to establish prayer, to pay Zakah, to fast Ramadan, and to perform Hajj to the House if you are able to find a way thereto." He said: "You have spoken the truth." We wondered how he asked him and affirmed his truthfulness. Then, he said: "Tell me about Imān (faith)." He said: "It is to believe in Allah, His angels, His books, His messengers, and the Last Day, and believe in the divine decree, the pleasant and unpleasant aspects thereof." Then, he said: "You have spoken the truth." Then, he said: "Tell me about ihsān." He said: "It is to worship Allah as if you see Him, for if you do not see Him, He sees you." He said: "Tell me about the Hour." He said: "The one questioned about it knows no more than the questioner." He said: "Then, tell me about its signs." He said: "The slave girl will give birth to her mistress, and you will see the barefoot, naked, and destitute herdsmen competing in constructing lofty buildings." Then, he departed. I stayed for a while, and then he said to me: "O 'Umar, do you know who the questioner was?" I said: "Allah and His Messenger know best." He said: "He was Jibrīl (Gabriel). He came to teach you your religion."
