You are not the first messenger sent.
Comfort for the Prophet ﷺ
Ibn Kathir says Allah was consoling His Messenger ﷺ after Quraysh rejected him. The surah introduction notes he had grown tired after years of effort. Allah reminds him that messengers came before him to earlier peoples.
You are the only one in the office who prays. Or the only one at home trying to keep the family calm. Others walked this before you, and Allah saw each of them.
Nobody has ever been in a spot as lonely as mine.
I am walking a path many before me walked, and they were not left alone.
Read a short story of one earlier prophet tonight and notice what he faced.
