Hadith 16:113
An-Nu’man bin al-Bashir (RAA) narrated that the Messenger of Allah (ﷺ) said:
“Verily supplication is worship.” Related by the four Imams and At-Tirmidhi graded it as Sahih,
وَعَنِ النُّعْمَانِ بْنِ بَشِيرٍ -رَضِيَ اَللَّهُ عَنْهُمَا- عَنِ النَّبِيِّ - صلى الله عليه وسلم -قَالَ: { إِنَّ اَلدُّعَاءَ هُوَ اَلْعِبَادَةُ } رَوَاهُ اَلْأَرْبَعَةُ, وَصَحَّحَهُ اَلتِّرْمِذِيُّ
