Is Salah behind a person who works in a bank valid

Q 1: If the Imam is a well-versed man, but does not offer Ud-hiyah (sacrificial animal offered by non-pilgrims) yearly, is this permissible?

Offering Ud-hiyah is a confirmed Sunnah for those who are able to sacrifice due to the Hadith narrated by Anas (may Allah be pleased with him) that the Prophet (peace be upon him) sacrificed two white rams with big horns. Related by Muslim in his Sahih (authentic) Book of Hadith. Offering Salah behind such an Imam is permissible.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
