Al-An'am 6:162
قُلْ إِنَّ صَلَاتِى وَنُسُكِى وَمَحْيَاىَ وَمَمَاتِى لِلَّهِ رَبِّ ٱلْعَـٰلَمِينَ
Qul inna salatee wanusukeewamahyaya wamamatee lillahi rabbialAAalameen
"Say, "Indeed, my prayer, my rites of sacrifice, my living and my dying are for Allāh, Lord of the worlds."
Al-An'am 6:162, translation by Sahih International
A short reflection
My prayer, my rites, my living, and my dying are for Allah, the whole life, not just the quiet moments.
