Section V: Description of Istinja’

Firstly: Ruling of urinating while standing
It is permissible to urinate standing up if one is safe from spreading filth and from being seen, [67] The origin is urinating while sitting, as it’s the most prevalent of the Prophet’s actions ﷺ. and this is the correct position of Hanbalis, an opinion among the Malikis, and a group from the Salaf. It is the choice of Ibn al-Mundhir, al-Nawawi, al-Shawkani, Ibn Baz, and Ibn `Uthaymin.

Secondly: Cleaning with water
There is no particular number of times required when cleaning with water, and what judges the amount is when full cleanliness takes place. This is the position of the majority: Hanafis, Malikis, Shafi`is, and a narration from Ahmad.

Thirdly: Cleanliness using stones and the like
Three wipes suffice, and if full cleanliness does not take place then one increases. A trace which is only removeable with water may be overlooked. This is the position of the Shafi`is, Hanbalis, the choice of Ibn al-Mundhir, Ibn Hazm, Ibn Taymiyyah, Ibn Baz, and Ibn `Uthaymin.

Fourthly: Ruling of performing istinja’ with the right hand
Scholars have differed over the ruling of performing istinja’ with the right hand according to two views:
First: It is that it is makruh to perform istinja’ with the right hand, and this is by agreement of the four schools of jurisprudence. [68] Al-Nawawi said: “The majority are upon that it is a prohibition of etiquette as opposed to one of impermissibility.” Sharh Sahih Muslim (156/3)
Second: It is that it is haram to perform istinja’ with the right hand. This is the position of the Zahiris, an opinion among the Shafi`is, the choice of Ibn `Abd al-Barr, Ibn Taymiyyah, al-Shawkani, and Ibn Baz.

Fifthly: What is not legally mandated when relieving oneself flicking the penis
Flicking [69] Natr refers to flicking, jerking, or twitching, and is contextually the aggressive moving back and forth of the penis until there is no urine left in the urethra. the penis after urinating is not legally mandated. This is the choice of Ibn Taymiyyah, Ibn al-Qayyim, Ibn Baz, and Ibn `Uthaymin.
Remaining more than what is necessary:
It is makruh to remain in the place of relieving oneself for more time than is necessary, and this is the position of the majority: Hanafis, Malikis, Shafi`is, and a narration from the Hanbalis.
