Hadith 623623 - وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «إِنَّ طَاعَةَ اَللَّهِ عَزَّ وَ جَلَّ خِدْمَتُهُ فِي اَلْأَرْضِ وَ لَيْسَ شَيْءٌ مِنْ خِدْمَتِهِ يَعْدِلُ اَلصَّلاَةَ فَمِنْ ثَمَّ نَادَتِ اَلْمَلاَئِكَةُ زَكَرِيَّا عَلَيْهِ اَلسَّلاَمُ « وَ هُوَ قٰائِمٌ يُصَلِّي فِي اَلْمِحْرٰابِ »
Hadith.623 - Imam Jafar ibn Muhammad Al-Sadiq (as) said:
"Obedience to Allah (swt), the Mighty and Majestic, is to serve Him on earth, and there is nothing among His acts of service that equals prayer. This is why the angels called out to Zakariya (as) 'while he was standing in prayer in the sanctuary' (Surah Ale ‘Imran 3:39)”.
