What is it recommended to do when an eclipse occurs?
It is recommended to take a bath (ghusl), to give charity, seek forgiveness and bestow prayers upon the Prophet ﷺ in abundance. It is also recommended to pray two rak`ats (in congregation). The best way of performing it is that be in each rak`at two standings in which one recites the Qur’an and two bows (ruku`). It is recommended that there be two khutbahs after the rak`ats (similar to Jumah).
