SUYUTI 20274a:
from Kurdūs from his father —
"Whosoever livens up (staying awake in the night prayer and supplication) the two nights of ʿĪd, and the night of the middle of ˹the month of˺ Shaʿbān, his heart will not die when the hearts die (i.e. out of the fear of the Day of Judgement)."
السيوطي ٢٠٢٧٤a:
عن كردوس عن أبيه —
«مَنْ أَحْيَا لَيلَتِى الْعِيدِ، ولَيلَة النِّصْفِ مِنْ شَعْبَانَ لَمْ يمُتْ قَلبُهُ يَوْمَ تَمُوتُ الْقُلُوبُ۔»
