Narrated Abu Huraira reported God’s messenger as saying:
“The stomach is the tank of the body and the veins go down to it. When the stomach is healthy the veins come back in a healthy condition, but when it is in a bad condition they return diseased.”
‘A'isha told that God’s messenger asked her, “Have the mugharribun been seen among you?”
She asked what that meant and he replied, “They are those in whom is a strain of the jinn.”*
Abu Dawud transmitted it.
* Mirqat, iv, 514, says this happens if a man neglects to mention God when he has sexual intercourse with his wife.
When God’s messenger was praying one night he placed his hand on the ground and was stung by a scorpion, so he struck it with his sandal and killed it. Then when he departed he said:
“God curse the scorpion! It does not leave alone one who is praying or anyone else, or a prophet or anyone else.”
He then called for salt and water, and putting it in a vessel he began to pour it over his finger where it had stung him and wipe it, seeking refuge in God by reciting the Mu’awwidhatan.
Baihaqi transmitted the two traditions in Shu’ab al-iman.
Abu Sa'id al-Khudri told that God’s messenger used to seek refuge in God from jinn and the evil eye in men till the Mu’awwidhatan* came down, after which he made use of them and abandoned everything else.
Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a hasan gharib tradition.
