It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) in the same way. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) never took off his shoes during prayer except once. When he (peace and blessings be upon him) took off his shoes, the people also took theirs off. He (peace and blessings be upon him) asked: "What is the matter with you (why did you take off your shoes)?" They said: You took yours off, so we took ours off. He (peace and blessings be upon him) said: "Jibril (peace be upon him) informed me that there was filth (or something harmful) on them." This hadith is sahih (authentic) on the condition of Imam Bukhari, since he used Abdullah bin al-Muthanna as evidence, but the two Shaykhs did not record it. Its supporting narration (shahid) is the well-known hadith of Maymun al-A'war.

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) took off his sandals during the prayer, so the people behind him also took off their sandals. He (peace and blessings be upon him) asked: "What made you take off your sandals?" They said: "We saw you take them off, so we took ours off too." He (peace and blessings be upon him) said: "Indeed, Jibril informed me that there was filth on one of them, so I took them off for that reason. So do not take off your sandals (without cause)."

It is narrated from Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) that whenever the Messenger of Allah (peace and blessings be upon him) went to relieve himself, he would go far away. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it. Its supporting report (shahid) is the hadith of Jabir (may Allah be pleased with him).

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that whenever the Messenger of Allah (peace and blessings be upon him) intended to relieve himself, he would go so far away that no one could see him.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) was asked about sea water, and he (peace and blessings be upon him) said: "Sea water is pure (and purifying)." This hadith is sahih (authentic) on the condition of Imam Muslim, and its supporting reports are many, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man asked the Messenger of Allah (peace and blessings be upon him): "O Messenger of Allah, we travel by sea and carry a little water with us; if we use it for ablution, we will go thirsty. May we perform ablution with sea water?" The Messenger of Allah (peace and blessings be upon him) said: "Its water is pure and its dead (animals) are lawful." Imam Malik narrated it, and other narrators have also corroborated him in it.

A similar report (to the previous hadith) concerning sea water is narrated from the Prophet (peace and blessings be upon him) through Sayyiduna Abu Hurayrah (may Allah be pleased with him).

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that some people who travelled by sea came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, we travel on the sea and take some water with us; if we use it for ablution, we will go thirsty. Is it proper for us to perform ablution with sea water?" The Messenger of Allah (peace and blessings be upon him) said: "Its water is pure and its dead (animals) are lawful."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him): One day we were sitting with the Messenger of Allah (peace and blessings be upon him) when a fisherman came and said: "O Messenger of Allah, we go out to sea for fishing, and one of us takes a water vessel with him, hoping to catch something soon. Sometimes he does find it so, and sometimes he does not find any catch until he reaches a place at sea he never thought he would reach. There he may have a wet dream or need to perform ablution. Now if he performs the ritual bath (ghusl) or ablution with this (drinking) water, he fears perishing from thirst. So in your view, may we take the ritual bath or perform ablution with sea water?" The Messenger of Allah (peace and blessings be upon him) said: "Take the ritual bath from it and perform ablution with it, for its water is pure and its dead (animals) are lawful." Imam Muslim used al-Julah Abu Kathir as evidence.
