What is the validity of the statement by some scholars: “Whoever hears the call to prayer and is late to catch the opening takbir is sinful”?

Question:
May Allah reward you, Your Eminence, father. The questioner says: Some scholars, based on the principle that “whatever is necessary for the completion of an obligatory act is itself obligatory,” state that one who is late to catch the opening takbir with the imam, having heard the adhan, is sinful in accordance with this principle. Is this statement correct?

Answer:
No, this is an opinion from his own mind. I do not think any scholar has said this. Scholars encourage attending the opening takbir, which is a virtue. If one misses it, there is no sin. Rather, if he arrives and the imam is bowing, and he bows with him, he catches the rak'ah. He catches the rak'ah. Yes.
