Prophet Muhammad (saws) said, 'Verily there is a Surah in the Quran which has 30 Ayats. It had interceded for a person until he was forgiven. That Surah is 'Tabarak allathi biyadihil mulk'. [Tirmidhi]
It's also called al-Waqiya (the Protector), al-Munjiyya (the Rescuer), al-Mani'a (the Defender), and al-Mujadila (the Arguer) because it argues on behalf of the one who knows it when he is in the grave.
Prophet Muhammad (saws) never used to sleep without reciting Surat al-Mulk, and he wished for it to be in the heart of every believer. Think of how easy it is to take 10 mins each night to recite it and at the end of your life, being so pleased with yourself because of its great benefits. Here is my favourite recitation, listen to it tonight before sleeping inshallah: http://www.youtube.com/watch?v=SQmbq_YXp...
My question is, what other ways are you preparing for a good death? Or have you not really thought of it enough to prepare? Is death a depressing topic to you?
Surely death is a blessing for a believer who is prepared, those who passed on are probably happier than we are now inshallah. May Allah make us all have beautiful deaths where the angels welcome out our souls with garments from Jannah, smell of musk, and glad tidings from Allah!
