Al-Mukhtasar
فَسَبِّحْ بِحَمْدِ رَبِّكَ وَكُن مِّنَ ٱلسَّـٰجِدِينَ ﴿٩٨﴾
So resort to Allah by declaring His transcendence from everything not appropriate for Him, and by praising Him with the attributes of His perfection; and be one of those who worship Allah and pray to Him. In that there is a cure for the strain on your heart.
