The aforementioned had?th clearly states the prohibition of trespassing other people. The apparent specification of this prohibition indicates that it is only prohibited on Fridays. However, this specification only presents what usually happens on such a day when the number of praying muslims is great.

Accordingly; the ruling applies to all Salaw?t and this is the apparent meaning of the had?th’s words that state the reason of this prohibition, namely causing harm to others. Thus, the same ruling applies to knowledge gatherings and the like.

Having stated the aforementioned ruling, Ibn Hajar excluded trespassing others to fill gabs existing in the first rows [when doing Sal?t]; one’s trespassing is forgiven in such a case for it takes place because of other people’s negligence to do what they are told to do [i.e. getting close to each other when standing in the rows]’.

Tresspassing other people on Friday causes one’s reward to loss -as mentioned in Ibn ‘Amru’s had?th; the prophet ( - ) said: ‘Whoever commits Laghw or tresspasses other people, his Jumu‘ah Sal?t will turn into Thuhr Sal?t’. (2)

Ibn Wahb -one of the had?th narrators- interpreted the had?th that one’s Sal?t is valid but one’s Jumu‘ah reward is lost. (3)

[12/ 58] Doing Ihtib?’ while the Khat?b is delivering Khutbah:

Ahmad, Ab? Daw?d, At-Tirmith? and Al-H?kim narrated from Mu‘?th that the prophet ( - ) forbade that one does Ihtib?’ while the Khat?b is delivering the Khutbah. Ihtib?’ means: putting one’s legs so close to one’s belly and wrap them all with one garment with the back - it also applies to arms. This sit causes one’s private parts to be displayed and causes one to sleep. Be ware, dear muslim, of doing such an act in order to retain the rewards given to you.
