The Messenger of Allah ﷺ said to me: Spend, and do not calculate, or otherwise Allah would also calculate in your case.  

عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ ؓ قَالَتْ قَالَ لِي رَسُولُ اللَّهِ ﷺ أَنْفِقِي أَوِ انْضَحِي أَوِ انْفَحِي وَلاَ تُحْصِي فَيُحْصِيَ اللَّهُ عَلَيْكِ  

Spend and do not calculate, (for) Allah would calculate in your case; and do not hoard, otherwise Allah would be withholding from you.  

قَالَ رَسُولُ اللَّهِ ﷺ انْفَحِي أَوِ انْضَحِي أَوْ أَنْفِقِي وَلاَ تُحْصِي فَيُحْصِيَ اللَّهُ عَلَيْكِ وَلاَ تُوعِي فَيُوعِيَ اللَّهُ عَلَيْكِ  

This hadith has been narrated on the authority of Asma' through another chain of transmitters.  

أَنَّ النَّبِيَّ ﷺ قَالَ لَهَا نَحْوَ حَدِيثِهِمْ  

Apostle of Allah, I have nothing with me, but only, that which is given to me by Zubair (for household expenses). Is there any sin for me if I spend out of that which is given to me (by Zabair)? Upon this he (the Holy Prophet) said: Spend according to your means; and do not hoard, for Allah will withhold from you.  

أَنَّهَا جَاءَتِ النَّبِيَّ ﷺ فَقَالَتْ يَا نَبِيَّ اللَّهِ لَيْسَ لِي شَىْءٌ إِلاَّ مَا أَدْخَلَ عَلَىَّ الزُّبَيْرُ فَهَلْ عَلَىَّ جُنَاحٌ أَنْ أَرْضَخَ مِمَّا يُدْخِلُ عَلَىَّ فَقَالَ ارْضَخِي مَا اسْتَطَعْتِ وَلاَ تُوعِي فَيُوعِيَ اللَّهُ عَلَيْكِ
