Time for the Duha (Forenoon Optional) Prayer

Abu Qatadah (May Allah be pleased with him)reported:
The Messenger of Allah ﷺ said, "When anyone of you enters the mosque, he should perform two Rak'ah (of voluntary prayer) before sitting."

[Al-Bukhari and Muslim].

وعن أبي قتادة رضي الله عنه قال: قال رسول الله ﷺ: " إذا دخل أحدكم المسجد فلا يجلس حتى يصلي ركعتين". ((متفق عليه)).
