Sunan at-Tirmithiy كتاب الدعوات باب ما يقول إذا خرج من بيته
حَدَّثَنَا أَبُو كُرَيْبٍ حَدَّثَنَا أَبُو مُعَاوِيَةَ عَنِ الأَعْمَشِ عَنْ أَبِى صَالِحٍ عَنْ أَبِى هُرَيْرَةَ رضى الله عنه قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لأَنْ أَقُولَ سُبْحَانَ اللَّهِ وَالْحَمْدُ لِلَّهِ وَلاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ أَحَبُّ إِلَىَّ مِمَّا طَلَعَتْ عَلَيْهِ الشَّمْسُ. قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ.
The Messenger of God, peace and blessings of God be upon him, said, "For me to say, 'Exalted is God; praise is to God; there is no god except Allāh (1); and God is the greatest' is dearer to me than everything under the sun."
(1) Allāh is the Arabic name for the One and Only God, the same God shared by all monotheistic faiths (the name Allāh is often used by Arabic-speaking Christians and Jews). The name Allāh encompasses all the divine names and attributes of the Lord of the worlds, and hence has vast scopes of meaning. It is for this reason that Muslims consider it unique. Unlike the word 'God', Allāh in Arabic has no inflections of gender or number.
