النضر عن محمد بن سنان عن موسى بن بكر عن زرارة عن أبي عبيد الله عليه السلام قال قال: داود النبي عليه السلام لأعبدن الله اليوم عبادة ولا قرأ قراءة أحبت لم افعل مثلها قط فدخل محرابه ففعل فلما فرغ من صلاته إذا هو بضفدع في المحراب فقال له يا دود: أعجبك اليوم ما فعلت من عبادتك وقراءتك؟ فقال نعم فقال: لا يعجبنك فانى اسبح الله في كل ليلة الف تسبيحة يتشعب لي مع كل تسبيحة ثلاثة آلاف تحميدة وانى لاكون في قعر الماء فيصوت الطير في الهواء فاحسبه جائعا فأطفو له على الماء ليأكلني ومالي ذنب.
4.Al-Naḍr narrated from Muḥammad ibn Sinān, from Mūsā ibn Bakr, from Zurārah, from Abū ʿAbdillāh  who said, “Prophet Dāwūd  said, ‘I will surely worship Allah today with such a worship, and will recite such a lovely recital, the likes of which I have never done before.’ So he entered his prayer niche and did so. When he had completed his prayer, he [suddenly] saw a frog in the prayer niche. It said to him, ‘O Dāwūd, are you pleased with yourself today due to your worship and recitation?’ ‘Yes,’ he replied. It said, ‘Do not be pleased [or impressed] by it, for verily I glorify Allah every night one thousand times, and with each glorification of mine three thousand praises branch out. And [at times] when I am in the depths of the water and a bird makes a sound in the air, I assume that it might be hungry so I come up to the surface of the water in order for it to eat me, while having committed no sin [to deserve that].’”
