The Prophet ﷺ said: Nothing but Paradise must be begged for Allah's sake.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يُسْأَلُ بِوَجْهِ اللَّهِ إِلاَّ الْجَنَّةُ  

The Prophet ﷺ said: If anyone seeks protection in Allah's name, grant him protection; if anyone begs in Allah's name, give him something; if anyone gives you an invitation, accept it; and if anyone does you a kindness, recompense him; but if you have not the means to do so, pray for him until you feel that you have compensated him.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اسْتَعَاذَ بِاللَّهِ فَأَعِيذُوهُ وَمَنْ سَأَلَ بِاللَّهِ فَأَعْطُوهُ وَمَنْ دَعَاكُمْ فَأَجِيبُوهُ وَمَنْ صَنَعَ إِلَيْكُمْ مَعْرُوفًا فَكَافِئُوهُ فَإِنْ لَمْ تَجِدُوا مَا تُكَافِئُونَهُ فَادْعُوا لَهُ حَتَّى تَرَوْا أَنَّكُمْ قَدْ كَافَأْتُمُوهُ  

If anyone asks you refuge for Allah’s sake give him refuge; and if anyone asks you (for something) for Allah’s sake, give him. Sahl and Sulaiman said: if anyone calls you, respond to him. The Agreed version goes; if you do not afford to compensate him, pray Allah for him until you know that you have compensated him.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اسْتَعَاذَكُمْ بِاللَّهِ فَأَعِيذُوهُ وَمَنْ سَأَلَكُمْ بِاللَّهِ فَأَعْطُوهُ وَقَالَ سَهْلٌ وَعُثْمَانُ وَمَنْ دَعَاكُمْ فَأَجِيبُوهُ ثُمَّ اتَّفَقُوا وَمَنْ آتَى إِلَيْكُمْ مَعْرُوفًا فَكَافِئُوهُ قَالَ مُسَدَّدٌ وَعُثْمَانُ فَإِنْ لَمْ تَجِدُوا فَادْعُوا اللَّهَ لَهُ حَتَّى تَعْلَمُوا أَنْ قَدْ كَافَأْتُمُوهُ
