The orphans, poor and travellers are the ones from the progeny of the Holy Prophet (s.a.w.). And so khums cannot reach anyone apart from these’. وَآتِ ذَا الْقُرْبَى حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ وَلاَ تُبَذِّرْ تَبْذِيرًا [Shakir 17:26] And give to the near of kin his due and (to) the needy and the wayfarer, and do not squander wastefully.
In Tafseer Saafi it has been reported that the ‘near ones’ referred to in this Verse are those near to the Holy Prophet (s.a.w.) and this verse has specially been revealed for Lady Fatimah Zahra (a.s.). The Holy Prophet (s.a.w.) had reserved the garden of Fidak for her (a.s.). The poor and travellers mentioned here are the one from her (a.s.) progeny.
فَآتِ ذَا الْقُرْبَى حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ ذَلِكَ خَيْرٌ لِّلَّذِينَ يُرِيدُونَ وَجْهَ اللَّهِ وَأُوْلَئِكَ هُمُ الْمُفْلِحُونَ [Shakir 30:38] Then give to the near of kin his due, and to the needy and the wayfarer; this is best for those who desire Allah's pleasure, and these it is who are successful.
In Tafseer Saafi it has been reported from Imam Muhammad Baqir (a.s.) and Imam Ja’far Al Sadiq (a.s.) that when this verse was revealed, the Holy Prophet (s.a.w.) gave the garden of fidak to Lady Fatima Zahra (a.s.) and gave her the control of it.
مَّا أَفَاء اللَّهُ عَلَى رَسُولِهِ مِنْ أَهْلِ الْقُرَى فَلِلَّهِ وَلِلرَّسُولِ وَلِذِي الْقُرْبَى وَالْيَتَامَى وَالْمَسَاكِينِ وَابْنِ السَّبِيلِ كَيْ لَا يَكُونَ دُولَةً بَيْنَ الْأَغْنِيَاء مِنكُمْ وَمَا آتَاكُمُ الرَّسُولُ فَخُذُوهُ وَمَا نَهَاكُمْ عَنْهُ فَانتَهُوا وَاتَّقُوا اللَّهَ إِنَّ اللَّهَ شَدِيدُ الْعِقَابِ [Shakir 59:7] Whatever Allah has restored to His Messenger from the people of the towns, it is for Allah and for the Messenger, and for the near of kin and the orphans and the needy and the wayfarer, so that it may not be a thing taken by turns among the rich of you, and whatever the Messenger gives you, accept it, and from whatever he forbids you, keep back, and be careful of (your duty to) Allah; surely Allah is severe in retributing (evil): It has been mentioned in Tafseer Saafi quoting from Al Kafi that Imam Ali (a.s.) said: ‘The near ones mentioned here are us and the orphans and the needy and the wayfarer are the ones from us.
This is why Allah (s.w.t.) has kept no share for us in charity and made it prohibited to us. Allah (s.w.t.) has honoured us and the Holy Prophet (s.a.w.) by not letting us eat the dirt and filth of the people.
