Tafsir of Al-Hijr 15:97

{بما يقولون} By what they say: the statements of those who slander you and the Qur’an.

{فسبح} So glorify: seek refuge in Allah regarding what has afflicted you. Seeking refuge in Allah is through constant remembrance and frequent prostration; it will suffice you and remove your distress.

{بحمد ربك وكن من الساجدين} Continue in the worship of your Lord.

{حتى يأتيك اليقين} Until the certainty comes to you: meaning death. That is, as long as you are alive, do not neglect worship.

It is narrated from the Prophet (ﷺ) that whenever a matter distressed him, he would hasten to prayer.

It is narrated from the Messenger of Allah (ﷺ): "Whoever recites Surah al-Hijr will have a reward of ten good deeds for every Muhajir, Ansar, and those who mocked Muhammad (ﷺ)."
