Shu’bah narrated that I heard Mughira say that Abu Dhubyan sent a messenger to Imam Ibrahim (may Allah have mercy on him) to ask about a menstruating woman: can she help a sick person perform ablution? Ibrahim (may Allah have mercy on him) replied: Yes. He asked: Can she support him during prayer? He replied: No. Shu’bah said: I asked Mughira: Did you hear this directly from Ibrahim (may Allah have mercy on him)? He said: No. Imam Darimi (may Allah have mercy on him) said: «وتسنده» : That is, can she support him during prayer? (To which he replied that not during prayer).
