Should one wait for the father to perform ablution in order to pray in congregation, or should the prayer be commenced immediately upon his arrival?

Among the prayers are those for which it is not sunnah to hasten their performance, such as the Isha (night) and Dhuhr (noon) prayers in hot weather. For these, one may wait for the number of worshippers to increase, as long as the time does not become too short or the delay does not cause hardship. It is permissible to wait for one's father or others. As for prayers for which it is sunnah to hasten their performance, such as Asr (afternoon), Maghrib (sunset), and Fajr (dawn) prayers, it is not sunnah to delay them, nor should one wait for anyone for them. Some scholars have recommended waiting for people of knowledge and virtue, or for those who are regular in attending the congregational prayer, provided it does not cause hardship to others. Waiting for someone to join the prayer involves three situations: before starting the prayer, during the bowing (ruku), and in situations where the rakah cannot be caught up with, such as prostration (sujud). Waiting for someone to join before commencing the prayer is not sunnah except for prayers for which it is sunnah to delay their performance, such as Isha. It has been deemed commendable to wait for a person of honor, or one with leadership in religious or worldly matters, if they always pray in the mosque, provided that it does not cause hardship to the worshippers.
