Is one who listens to the prayer upon the Prophet, peace and blessings be upon him, from a mobile phone and does not repeat it, sinful, knowing that a colleague said that the supplication "He is ruined and has lost who, when I am mentioned in his presence, does not invoke blessings upon me" might befall him?

Texts have been narrated condemning those who do not send blessings upon the Prophet, peace and blessings be upon him, when his name is mentioned, such as: "May the nose of a man be rubbed in the dust, in whose presence I am mentioned and he does not send blessings upon me," and "The miser is he in whose presence I am mentioned and he does not send blessings upon me." Sending blessings upon the Prophet when his name is mentioned is recommended (mustahabb) and not obligatory (wajib) according to the majority of scholars, and it suffices to mention it once if the mention is repeated within the same gathering. Listening to recorded voices, including the blessings upon the Prophet, does not take the ruling of listening to live voices. Therefore, you are not obliged to send blessings when you hear the reminder from a mobile phone, but it is a recommended act and has a great reward.
