Short answer
Yes. Fostering a child in need is a highly rewarded act, close to the kafalah (sponsorship) that Islam praises. Foster care already keeps the child's own name and lineage, which matches Islamic rules. Carers must keep mahram and privacy rules as the child grows, and protect their own faith in the home.
Taking in and caring for a child who needs a home is a virtue, and becomes wajib when the child would otherwise be lost. The child keeps their own lineage and is not a mahram to the carers through fostering alone.
The four schools agree on this.
Explanation
The Prophet ﷺ said that he and the one who looks after an orphan will be together in Paradise like two joined fingers, and he raised Zayd ibn Harithah in his own home. Fostering is one of the clearest ways to earn that reward today. Fostering services in the UK and elsewhere often say they need more Muslim carers for Muslim children.
Why fostering fits Islamic rules well:
- The child keeps their birth surname and identity. See the adopted child's surname.
- Foster care is usually temporary, with the aim of returning the child to family where safe.
- Carers are paid allowances for the child's costs, which is permissible.
Things to plan for:
- Mahram and privacy: as an unrelated child nears puberty, hijab and seclusion rules apply. For babies, nursing within two years can create mahram ties. See is an adopted child mahram.
- A child of another faith: you may foster and care for them with kindness. Agencies usually ask carers to respect a child's background; a Muslim carer should not take part in another religion's worship, so discuss this with the agency before placement.
- Halal home: agencies normally accept a halal diet and a Muslim household routine.
- Long-term care: special guardianship or kafalah-style arrangements suit Muslims better than adoption orders that change the child's legal parentage.

The evidence
Quran, Surah Al-Ahzaab 33:5
ٱدْعُوهُمْ لِءَابَآئِهِمْ هُوَ أَقْسَطُ عِندَ ٱللَّهِ ۚ فَإِن لَّمْ تَعْلَمُوٓا۟ ءَابَآءَهُمْ فَإِخْوَٰنُكُمْ فِى ٱلدِّينِ وَمَوَٰلِيكُمْ ۚ وَلَيْسَ عَلَيْكُمْ جُنَاحٌۭ فِيمَآ أَخْطَأْتُم بِهِۦ وَلَٰكِن مَّا تَعَمَّدَتْ قُلُوبُكُمْ ۚ وَكَانَ ٱللَّهُ غَفُورًۭا رَّحِيمًا ﴿٥﴾
Call them by [the names of] their fathers; it is more just in the sight of Allah. But if you do not know their fathers - then they are [still] your brothers in religion and those entrusted to you. And there is no blame upon you for that in which you have erred but [only for] what your hearts intended. And ever is Allah Forgiving and Merciful.
A fostered child keeps his own lineage.
Quran, Surah Al-Baqara 2:220
فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ ۗ وَيَسْـَٔلُونَكَ عَنِ ٱلْيَتَٰمَىٰ ۖ قُلْ إِصْلَاحٌۭ لَّهُمْ خَيْرٌۭ ۖ وَإِن تُخَالِطُوهُمْ فَإِخْوَٰنُكُمْ ۚ وَٱللَّهُ يَعْلَمُ ٱلْمُفْسِدَ مِنَ ٱلْمُصْلِحِ ۚ وَلَوْ شَآءَ ٱللَّهُ لَأَعْنَتَكُمْ ۚ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌۭ ﴿٢٢٠﴾
To this world and the Hereafter. And they ask you about orphans. Say, "Improvement for them is best. And if you mix your affairs with theirs - they are your brothers. And Allah knows the corrupter from the amender. And if Allah had willed, He could have put you in difficulty. Indeed, Allah is Exalted in Might and Wise.
Whatever improves the life of a child without parents is good.
Sahih al-Bukhari 5304
Sahih... أنا وكافل اليتيم في الجنة هكذا ...
"I and the one who looks after an orphan will be in Paradise like this."
The reward for caring for a child without parents.
Where the ruling is recorded
- al-Hidaya, Kitab al-Laqit (the foundling). Taking in an abandoned child is recommended, and obligatory if the child would otherwise perish; the child's lineage is not changed.
