Question 183: When some Muslim brothers set out on a journey or to perform ‘Umrah, they ask one of them to recite the Wird (portion recited with consistency) of the morning and the evening reported from the Messenger of Allaah (peace be upon him), while the rest of the group listen to him. What is the ruling on this?
Answer: The Messenger of Allaah (peace be upon him) used to say certain forms of Dikr (Remembrance of Allaah) and Du’aa’ (supplication) through which he supplicated to Allaah every night and day in private. His Sahaabah (Companions) heard them and learned them from him, and they used to supplicate to Allaah through them every night and day, each one in private, following the example of the Messenger of Allaah (peace be upon him). As far as we know, it was not authentically reported that he (peace be upon him) or his Sahaabah (may Allaah be pleased with them) used to say these Adkaar (Remembrances of Allaah) and Du’aa’s collectively, where all of them read simultaneously, or one of them read and the others listened. A Muslim should follow the example of the Messenger of Allaah (peace be upon him) and his Sahaabah (may Allaah be pleased with them) in their Dikr, Du’aa’ and all what he (peace be upon him) has ordained. All goodness lies in following him, and all evil lies in contradicting him and taking this as a regular habit and a Bidd`ah (innovation in religion)... read more here.
