What is the ruling of donating blood in a non-Muslim place of worship?
Alhamdulillah, praise and thanks to Allah for the countless blessings He has blessed us all with. Blessings and salutations to the Prophet Muhammad PBUH, his wives, his family, companions and all those that follow his teachings to the day of judgement.
Donating blood is permissible, even a Sunnah and a highly commendable act in Islam because it is an act of helping others towards righteousness. This is in accordance with the saying of Allah SWT:
وَتَعَاوَنُوا عَلَى الْبِرِّ وَالتَّقْوَىٰ
And cooperate in righteousness and piety
Surah al-Ma’idah (2)

However, the ruling of entering places of worship of non-Muslims is something that is disputable among scholars. Refer Irsyad Fatwa #248: The Ruling of Entering Places of Worship for Other Religion and Attending Christian Wedding Ceremony in Church
In short, the final opinion in the madhhab al-Shafi’e is the ruling of entering the places of worship of non-Muslims is haram if one enters without permission when there are idols or pictures which are worshipped, or if entering the place honours the religion. Some scholars permit it even with the presence of idols and pictures on the condition of not worshipping their eminence or entering without permission.
This is in line with a hadith narrated from Abi Talhah RA, where the Prophet PBUH said:
لاَ تَدْخُلُ الْمَلاَئِكَةُ بَيْتًا فِيهِ كَلْبٌ وَلاَ صُورَةُ تَمَاثِيلَ
"Angels (of Mercy) do not enter a house wherein there is a dog or a picture of a living creature (a human being or an animal).
Sahih al-Bukhari (3225) and Sahih Muslim (2016)

Based on the above facts and explanation, we are inclined to the opinion that it is permissible for a Muslim to participate in the blood donation held at the non-Muslim places of worship because there is a need, on the condition of that it is done with permission as well as not following any ritual which is the eminence of the religion. The same is when the blood donation is not for the purpose of promoting the religion because helping towards disbelief is also a disbelief. It is best for a Muslim to donate blood in places which are away of any fitnah.
May this explanation gives understanding to the questioner. We pray to Allah SWT to accept all our good deeds. Ameen.
