Scholars differ General principles
Most contemporary councils permit donating an organ that a person can live without, such as a kidney, to save a life, and also permit organs after death with consent. They stress that life is saved (5:32), that no payment is taken, and that there is no harm to the donor. A few scholars forbid it because the body belongs to Allah.
مِنْ أَجْلِ ذَٰلِكَ كَتَبْنَا عَلَىٰ بَنِىٓ إِسْرَٰٓءِيلَ أَنَّهُۥ مَن قَتَلَ نَفْسًۢا بِغَيْرِ نَفْسٍ أَوْ فَسَادٍۢ فِى ٱلْأَرْضِ فَكَأَنَّمَا قَتَلَ ٱلنَّاسَ جَمِيعًۭا وَمَنْ أَحْيَاهَا فَكَأَنَّمَآ أَحْيَا ٱلنَّاسَ جَمِيعًۭا ۚ وَلَقَدْ جَآءَتْهُمْ رُسُلُنَا بِٱلْبَيِّنَٰتِ ثُمَّ إِنَّ كَثِيرًۭا مِّنْهُم بَعْدَ ذَٰلِكَ فِى ٱلْأَرْضِ لَمُسْرِفُونَ ﴿٣٢﴾
因此，我对以色列的后裔以此为定制：除因复仇或平乱外，凡枉杀一人的，如杀众人；凡救活一人的，如救活众人。我的众使者。确已昭示他们许多迹象。此后，他们中许多人，在地方上确是过分的。
