Notes (Tafseer)

2458. This preface shows the fervent faith of Zakariya. Zakariya was a prophet of the Most High Allah. His office was in the Temple, and his relatives were his colleagues. But he found in them no true spirit of the service of Allah and man. He was filled with anxiety as to who would uphold the godly ideas he had in mind, which were strange to his worldly colleagues.
