4. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad ibn abu Nasr from someone who had asked abu ‘Abd Allah عليه السلام, has the following: “I once asked abu ‘Abd Allah عليه السلام, about the al-Qiblah (al-Ka‘bah) side of the wall of a Masjid from which sewage, in which people urinate, leaks. He (the Imam) said, ‘If the leakage is from the sewage, do not perform Salah (prayer) there; but if the leakage is from something else, it is not an offense to perform Salah (prayer) there.’”
