A man praying with traces of janabah on his garment

Zuyayd bin al-Salt said: If Sayyiduna Umar (may Allah be pleased with him) saw any trace of semen on his clothes, he would wash it; if no trace could be seen, he would sprinkle water on it; and he would repeat the prayer at the time of the forenoon (chasht).

Sulayman bin Yasar said: Sayyiduna Umar (may Allah be pleased with him) prayed the Fajr prayer, then went to a land of his at a place called al-Jurf. There he saw the trace of a wet dream on his clothes, so he took a ritual bath (ghusl) and repeated the Fajr prayer.

Aflah narrated from his father, who said: I prayed while there was a stain of janabah on my clothes, and Sayyiduna Ibn Umar (may Allah be pleased with them both) ordered me to pray again, so I repeated the prayer.

Ibrahim said, regarding a man who prays while there is a stain of janabah on his clothes: "His prayer is done; he does not need to repeat it."

Al-Hasan used to say: "If he realises it while the time of the prayer is still in, he should repeat it."

Sa'id bin al-Musayyib said: "Whoever prays with a trace of janabah (on his clothes) does not have to repeat it."

Ibrahim said: "If a person sees traces of blood or semen on his clothes, he should wash them and not repeat the prayer."
