[Machine] I came to the Messenger of Allah ﷺ and I said, "O Messenger of Allah, how does Allah revive the dead?" He said, "Have you not passed by a land that was barren, then you passed by it while it was fertile?" I said, "Yes." He said, "Thus is the revival." I said, "O Messenger of Allah, what is faith?" He said, "To testify that there is no deity worthy of worship except Allah alone, with no partners, and to testify that Muhammad is His servant and messenger, and that Allah and His messenger are more beloved to you than anyone else, and to prefer being burned in the fire rather than associating partners with Allah, and to love someone without any personal interest except for the sake of Allah. If you are such, then love of faith has entered your heart, just as the love of water enters the heart of a thirsty person on a scorching day." I said, "O Messenger of Allah, how can I know that I am a believer?" He said, "None of my Ummah, or this Ummah, is a servant who performs a good deed and knows that it is a good deed, and Allah rewards him with goodness for it, or performs an evil deed and knows that it is an evil deed, and seeks forgiveness from Allah for it, knowing that no one forgives sins except Him, except that he is a believer."  

أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ كَيْفَ يُحْيِي اللهُ الْمَوْتَى؟ قَالَ أَمَا مَرَرْتَ بِأَرْضٍ مِنْ أَرْضِكَ مُجْدِبَةٍ ثُمَّ مَرَرْتَ بِهَا مُخْصَبَةً؟ قَالَ نَعَمْ قَالَ كَذَلِكَ النُّشُورُ قَالَ يَا رَسُولَ اللهِ وَمَا الْإِيمَانُ؟ قَالَ أَنْ تَشْهَدَ أَنْ لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ وَأَنْ يَكُونَ اللهُ وَرَسُولُهُ أَحَبَّ إِلَيْكَ مِمَّاسِوَاهُمَا وَأَنْ تُحْرَقَ فِي النَّارِ أَحَبُّ إِلَيْكَ مِنْ أَنْ تُشْرِكَ بِاللهِ وَأَنْ تُحِبَّ غَيْرَ ذِي نَسَبٍ لَا تُحِبُّهُ إِلَّا لِلَّهِ ﷻ فَإِذَا كُنْتَ كَذَلِكَ فَقَدْ دَخَلَ حُبُّ الْإِيمَانِ فِي قَلْبِكَ كَمَا دَخَلَ حُبُّ الْمَاءِ لِلظَّمْآنِ فِي الْيَوْمِ الْقَائِظِ قُلْتُ يَا رَسُولَ اللهِ كَيْفَ لِي بِأَنْ أَعْلَمَ أَنِّي مُؤْمِنٌ؟ قَالَ مَا مِنْ أُمَّتِي أَوْ هَذِهِ الْأُمَّةِ عَبْدٌ يَعْمَلُ حَسَنَةً فَيَعْلَمُ أَنَّهَا حَسَنَةٌ وَأَنَّ اللهَ ﷻ جَازِيهِ بِهَا خَيْرًا وَلَا يَعْمَلُ سَيِّئَةً فَيَعْلَمُ أَنَّهَا سَيِّئَةٌ ويَسْتَغْفَرُ اللهَ ﷻ مِنْهَا وَيَعْلَمُ أَنَّهُ لَا يَغْفِرُ إِلَّا هُوَ إِلَّا وَهُوَ مُؤْمِنٌ
