AHMAD-ZUHD 753:
from Bāt Abū al-Dardāʾ al-Laylah Yuṣallī Fajaʿal Yabkī —
[Machine] Abu Darda spent the night praying and began to cry, saying, "O Allah, you have perfected my creation, so perfect my character." Until the morning, I asked, "O Abu Darda, what has been your supplication since last night?" He said, "O Umm Darda, a Muslim slave improves his character until his good character admits him into Paradise, and he deteriorates in character until his bad character admits him into Hell. Indeed, forgiveness is granted to a sleeping Muslim." I asked, "How is that, O Abu Darda?" He said, "His brother stands in prayer at night, invoking Allah, and Allah responds to him. He prays for his father, and Allah responds to him."

عن بات ابو الدرداء الليله يصلي فجعل يبكي —
بَاتَ أَبُو الدَّرْدَاءِ اللَّيْلَةَ يُصَلِّي فَجَعَلَ يَبْكِي وَيَقُولُ اللَّهُمَّ أَحْسَنْتَ خَلْقِي فَأَحْسِنْ خُلُقِي حَتَّى أَصْبَحَ فَقُلْتُ يَا أَبَا الدَّرْدَاءِ مَا كَانَ دُعَاؤُكَ مُنْذُ اللَّيْلَةِ إِلَّا فِي حُسْنِ الْخُلُقِ قَالَ يَا أُمَّ الدَّرْدَاءِ إِنَّ الْعَبْدَ الْمُسْلِمَ يَحْسُنُ خُلُقُهُ حَتَّى يُدْخِلَهُ حُسْنُ خُلُقِهِ الْجَنَّةَ وَيَسُوءُ خُلُقُهُ حَتَّى يُدْخِلَهُ سُوءُ خُلُقِهِ النَّارَ وَإِنَّ الْعَبْدَ الْمُسْلِمَ لَيُغْفَرُ لَهُ وَهُوَ نَائِمٌ قَالَ قُلْتُ وَكَيْفَ ذَاكَ يَا أَبَا الدَّرْدَاءِ؟ قَالَ يَقُومُ أَخُوهُ مِنَ اللَّيْلِ فَيَتَهَجَّدُ فَيَدْعُو اللَّهَ فَيَسْتَجِيبُ لَهُ وَيَدْعُو لِأَبِيهِ فَيَسْتَجِيبُ لَهُ
