[Machine] "From Abu Al-Jawza' (a companion of the Prophet): "Except for those who come to Allah with a sound heart." [Surah Ash-Shu'ara 89] He said: "There is no god but Allah."  

الزهد لأحمد:١٢١٣حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبُو بَكْرٍ حَدَّثَنَا يَحْيَى بْنُ وَاضِحٍ عَنْ يَحْيَى بْنِ عَمْرٍو عَنْ أَبِيهِ

عَنْ أَبِي الْجَوْزَاءِ {إِلَّا مَنْ أَتَى اللَّهَ بِقَلْبٍ سَلِيمٍ} [الشعراء 89] قَالَ لَا إِلَهَ إِلَّا اللَّهُ

quran:26:89

But only one who comes to Allah with a sound heart."  

except him who comes to God with a heart that is sound, ˹free˺ from idolatry and hypocrisy — and this is the heart of the believer, whom such ˹things˺ will avail.
القرآن:٢٦:٨٩

إِلَّا مَنْ أَتَى اللَّهَ بِقَلْبٍ سَلِيمٍ  

{إلا} لكن {من أتى الله بقلب سليم} من الشرك والنفاق وهو قلب المؤمن فإنه ينفعه ذلك.
