If a person is offering Salah and the phone rings, they may pick up the phone even if they go a few steps forward or backward or to the right or left provided that they face the Qiblah. He should say: "Subhana Allah (Glorified be Allah)" to inform the speaker on the phone. It is authentically reported in Sahih Al-Bukhari and Sahih Muslim
that the Messenger of Allah (peace be upon him) used to offer Salah while holding
Umamah, the daughter of his daughter. He used to put her down when he knelt down and carry her when he stood up.
According to the narration of
Muslim, "while leading people in Salah".
It is also
Ahmad and others
on the authority of
`Aishah (may Allah be pleased with her) that she said:
Once the Messenger (peace be upon him) was offering Salah while the door was closed. When I came, he (the Messenger) walked to open, then returned to his position. She added that the door was in the same direction of the Qiblah. (Part No. 7; Page No. 30)
Muslim also narrated that
The Messenger of Allah (peace be upon him) said: If something happens to you during prayer you should say 'Subhana-llah' (Glory be to Allah), and clapping is only for women.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
