وَالِارْتِثَاثُ: أَنْ يَأْكُلَ، أَوْ يَشْرَبَ، أَوْ يَتَدَاوَى،
Translation: Irtithath includes eating, drinking or receiving treatment,
Eating, drinking and receiving treatment are listed as signs of survival with a return to some acts of ordinary life following injury.
Tadawi means receiving medical treatment. The precise legal application to emergency aid needs the context and conditions of irtithath rather than an automatic extrapolation to every rescue procedure.
