May Allah عَزَّوَجَلَّ have mercy on him and forgive us without accountability for his sake.
صَلُّوۡا عَلَى الۡحَبِيۡب صَلَّى اللّٰهُ تَعَالٰى عَلٰى مُحَمَّد
Dear Islamic brothers! It has become obvious that serving parents is a great privilege. If they get pleased and pray for us, we will succeed. Listen to one more faith-refreshing parable and rejoice:
Sayyidunā Bāyazīd Bisṭāmī قُـدِّسَ سِـرُّهُ الـسَّـامِی said, ‘During a very cold night, my mother asked me to bring water. I went to bring a glass of water but she had fallen asleep when I came. I did not feel it appropriate to wake her up. Therefore, I stood near her holding the glass of water and waiting for her to wake up so that I would present it to her. I stood for quite a while. Meantime, some water spilled over my finger and froze, turning into ice.
When my mother woke up, I presented her the glass of water. My finger had adhered to the glass because of ice. As I detached my finger from the glass, its skin came off, causing bleeding. Seeing it, my mother asked, ‘What is this?’ I told her the whole story. Listening to it, she raised her hands and made Du’a, ‘O Allah عَزَّوَجَلَّ! I am pleased with him. You also get pleased with him.’
