Serving your parents in need is better than going to fight in the path of Allah

Jāhimah came to the Prophet ﷺ and said, "O Messenger of Allah! I want to go out and fight (in the path of Allah) and I have come to ask your advice." He said: "Do you have a mother?" He said: "Yes." He said: "Then stick with her, for Jannah is beneath her feet."  

أَنَّ جَاهِمَةَ جَاءَ إِلَى النَّبِيِّ ﷺ فَقَالَ: يَا رَسُولَ اللَّهِ أَرَدْتُ أَنْ أَغْزُوَ وَقَدْ جِئْتُ أَسْتَشِيرُكَ. فَقَالَ: «هَلْ لَكَ مِنْ أُمٍّ؟» قَالَ: نَعَمْ. قَالَ: «فَالْزَمْهَا، فَإِنَّ الْجَنَّةَ تَحْتَ رِجْلَيْهَا.»
