Question

                While I was praying my daughter 3 months of age started choking there was no one at home except for me so I had to stop my prayer to come to her aid is this haram what I had done or in emergency cases like this is it okay to stop your prayer.
Praise be to Allah.What
      you did was not haraam and was not a sin; in fact it was obligatory
      (waajib) upon you, because this comes under the heading of saving lives
      which is encouraged in Islam. Allaah says (interpretation of the meaning):
“… and if anyone saved a life, it would
      be as if he saved the life of all mankind …” (al-Maa’idah 5:32)
 It was reported from Ibn
      ‘Abbaas, from Murrah al-Hamadaani, from ‘Abd-Allaah and from a number
      of the Companions of the Messenger of Allaah concerning the Tafseer of
      this aayah: “…and if anyone saved a life means, saved someone from
      death, it would be as if he saved the life of all mankind in the eyes of
      the person whose life was saved.” (Tafseer
      al-Tabari, 6/199)
 Saving the life of a
      person whose life is protected in sharee’ah is obligatory (waajib) on
      whoever is able to do so. Savinga
      life is one of the five essentials which Islam came to protect (they are,
      life, sanity, wealth, religion and lineage). With regard to the prayer,
      you have to repeat it after you have helped the child. And Allaah knows
      best.
