Whosoever considers not to repeat ablution except if something is discharged or passed from exit (front or back private parts)
As is mentioned in the Statement of Allah تعالى: “… Or any of you comes from answering the call of nature…” (V.5:6). And ‘Ata’ said, “If a worm comes out of one’s anus or if a drop of discharge equal to the size of a louse comes out of one’s penis (then it is essential to repeat the ablution).” Jabir bin ‘Abdullah said, “If one laughs in Salat (prayer), he must repeat his Salat and not the ablution.” Al-Hasan said, “If someone takes out (cuts) some of his hair, cuts his nails, or removes his leather socks, he is not to repeat his ablution.” Abu Hurairah said, “It is not necessary to repeat ablution except on Hadath.” And Jabir stated, “The Prophet (ﷺ) ﷺ was in the battle of Dhat-ur-Riqa’ and a person was shot with an arrow and he bled profusely, but he bowed and prostrated and continued his Salat.” Al-Hasan said, “The Muslims used to offer Salat regularly with their wounds.” Tawus, Muhammad bin ‘Ali, ‘Ata, and the people of Hijaz say, “Bleeding does not necessitate the repetition of ablution.” Ibn ‘Umar squeezed one of his pimples and blood came out, but he did not repeat his ablution. Ibn Abi Aufa spat out blood but carried on with his Salat. Ibn ‘Umar and Al-Hasan said, “If anyone lets his blood out, then it is necessary for him to wash the cut area only.”
