1. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ’Isma‘il from af-Fadf ibn Shadhan from Hammad ibn ‘Isa from Hariz from Muhammad ibn Muslim who has said the following:

“I once asked abu ’Abd Allah , about the case of a woman who finds a discharge of yellow color during the time of her normal period of Hayd (menses). He (the Imam) said, ‘She must not perform Salah (prayer) during the time of her normal blood discharge due to Hayd (menses). If she experiences blood discharge of yellow color in a time, which is other than the time for her normal period of blood discharge due to Hayd (menses), she must take Wudu’ and perform Salah (prayer).’”
