It never happened that Messenger of Allah ﷺ was asked for anything and he said: No.  

مَا سُئِلَ رَسُولُ اللَّهِ ﷺ شَيْئًا قَطُّ فَقَالَ لاَ  

This hadith has been narrated on the authority of Jabir b. 'Abdullah through another chain of transmitters.  

سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ مِثْلَهُ سَوَاءً  

It never happened that Messenger of Allah ﷺ was asked anything for the sake of Islam and he did not give that. There came to him a person and he gave him a large flock (of sheep and goats) and he went back to his people and said: My people, embrace Islam, for Muhammad gives so much charity as if he has no fear of want.  

مَا سُئِلَ رَسُولُ اللَّهِ ﷺ عَلَى الإِسْلاَمِ شَيْئًا إِلاَّ أَعْطَاهُ قَالَ فَجَاءَهُ رَجُلٌ فَأَعْطَاهُ غَنَمًا بَيْنَ جَبَلَيْنِ فَرَجَعَ إِلَى قَوْمِهِ فَقَالَ يَا قَوْمِ أَسْلِمُوا فَإِنَّ مُحَمَّدًا يُعْطِي عَطَاءً لاَ يَخْشَى الْفَاقَةَ  

O people, embrace Islam. By Allah, Muhammad donates so much as if he did not fear want. Anas said that the person embraced Islam for the sake of the world but later he became Muslim until Islam became dearer to him than the world and what it contains.  

أَنَّ رَجُلاً سَأَلَ النَّبِيَّ ﷺ غَنَمًا بَيْنَ جَبَلَيْنِ فَأَعْطَاهُ إِيَّاهُ فَأَتَى قَوْمَهُ فَقَالَ أَىْ قَوْمِ أَسْلِمُوا فَوَاللَّهِ إِنَّ مُحَمَّدًا لَيُعْطِي عَطَاءً مَا يَخَافُ الْفَقْرَ فَقَالَ أَنَسٌ إِنْ كَانَ الرَّجُلُ لَيُسْلِمُ مَا يُرِيدُ إِلاَّ الدُّنْيَا فَمَا يُسْلِمُ حَتَّى يَكُونَ الإِسْلاَمُ أَحَبَّ إِلَيْهِ مِنَ الدُّنْيَا وَمَا عَلَيْهَا  

(By Allah) Messenger of Allah ﷺ gave me what he gave me (and my state of mind at that time was) that he was the most detested person amongst people in my eyes. But he continued giving to me until now he is the dearest of people to me.  

غَزَا رَسُولُ اللَّهِ ﷺ غَزْوَةَ الْفَتْحِ فَتْحِ مَكَّةَ ثُمَّ خَرَجَ رَسُولُ اللَّهِ ﷺ بِمَنْ مَعَهُ مِنَ الْمُسْلِمِينَ فَاقْتَتَلُوا بِحُنَيْنٍ فَنَصَرَ اللَّهُ دِينَهُ وَالْمُسْلِمِينَ وَأَعْطَى رَسُولُ اللَّهِ ﷺ يَوْمَئِذٍ صَفْوَانَ بْنَ أُمَيَّةَ مِائَةً مِنَ النَّعَمِ ثُمَّ مِائَةً ثُمَّ مِائَةً قَالَ ابْنُ شِهَابٍ حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ أَنَّ صَفْوَانَ قَالَ وَاللَّهِ لَقَدْ أَعْطَانِي رَسُولُ اللَّهِ ﷺ مَا أَعْطَانِي وَإِنَّهُ لأَبْغَضُ النَّاسِ إِلَىَّ فَمَا بَرِحَ يُعْطِينِي حَتَّى إِنَّهُ لأَحَبُّ النَّاسِ إِلَىَّ  

In case we get wealth from Bahrain, I would give you so much and so much; he made an indication of it with both his hands. Allah's Apostle ﷺ died before wealth from Bahrain came, and it fell to the lot of Abu Bakr after him. He commanded the announcer to make announcement to the effect that he to whom Allah's Apostle ﷺ had held out promise or owed any debt should come (to him). I came and said: Allah's Apostle ﷺ had said to me: In case there comes to us the wealth of Bahrain I shall give you so much, and so much. Abu Bakr took a handful (of the coins) and gave that to me once and asked me to count them I counted them as five hundred dinars and he said: Here is double of this for you.  

عَنْ جَابِرٍ أَحَدُهُمَا يَزِيدُ عَلَى الآخَرِ ح وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ وَاللَّفْظُ لَهُ قَالَ قَالَ سُفْيَانُ سَمِعْتُ مُحَمَّدَ بْنَ الْمُنْكَدِرِ يَقُولُ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ قَالَ سُفْيَانُ وَسَمِعْتُ أَيْضًا عَمْرَو بْنَ دِينَارٍ يُحَدِّثُ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ وَزَادَ أَحَدُهُمَا عَلَى الآخَرِ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ لَوْ قَدْ جَاءَنَا مَالُ الْبَحْرَيْنِ لَقَدْ أَعْطَيْتُكَ هَكَذَا وَهَكَذَا وَهَكَذَا وَقَالَ بِيَدَيْهِ جَمِيعًا فَقُبِضَ النَّبِيُّ ﷺ قَبْلَ أَنْ يَجِيءَ مَالُ الْبَحْرَيْنِ فَقَدِمَ عَلَى أَبِي بَكْرٍ بَعْدَهُ فَأَمَرَ مُنَادِيًا فَنَادَى مَنْ كَانَتْ لَهُ عَلَى النَّبِيِّ ﷺ عِدَةٌ أَوْ دَيْنٌ فَلْيَأْتِ فَقُمْتُ فَقُلْتُ إِنَّ النَّبِيَّ ﷺ قَالَ لَوْ قَدْ جَاءَنَا مَالُ الْبَحْرَيْنِ أَعْطَيْتُكَ هَكَذَا وَهَكَذَا وَهَكَذَا فَحَثَى أَبُو بَكْرٍ مَرَّةً ثُمَّ قَالَ لِي عُدَّهَا فَعَدَدْتُهَا فَإِذَا هِيَ خَمْسُمِائَةٍ فَقَالَ خُذْ مِثْلَيْهَا  

When Allah's Apostle ﷺ died, there came to Abfi Bakr wealth from al-'Ala' b. al-Hadrami. Abu Bakr said: He to whom Allah's Apostle ﷺ owed any debt or held out any promise should come to us; the rest of the hadith is the same.  

لَمَّا مَاتَ النَّبِيُّ ﷺ جَاءَ أَبَا بَكْرٍ مَالٌ مِنْ قِبَلِ الْعَلاَءِ بْنِ الْحَضْرَمِيِّ فَقَالَ أَبُو بَكْرٍ مَنْ كَانَ لَهُ عَلَى النَّبِيِّ ﷺ دَيْنٌ أَوْ كَانَتْ لَهُ قِبَلَهُ عِدَةٌ فَلْيَأْتِنَا بِنَحْوِ حَدِيثِ ابْنِ عُيَيْنَةَ
