I want to ask that a woman who is pregnant and face difficulty in doing sajdah while offering salah, can do sajdah on something like pillow or something else put at height from ground so as to make her sajdah easy as bending too much is causing pain etc. Please reply as it is very urgent. Is relaxation allowed in Islam for pregnant woman regarding salah?

بسم الله الرحمن الرحيم

(Fatwa: 993/794/D=09/1436)

Salah shall be valid if she does sajdah over a solid thing that is one span high. In case she faces difficulty in doing so then she should do sajdah while sitting with the gesture of head i.e. by bowing down her head.
