917/1 - Mu‘ādh ‘(may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “He whose last words are ‘La ilah illa Allah’ (there is no god but Allah) will enter Paradise.” [Narrated by Abu Dāwūd and Al-Hākim, who classified its Isnād as authentic]
918/2 - Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “Exhort your dying people to say: La ilah illa Allah (There is no god but Allah).” [Narrated by Muslim]
1) It shows the merit of monotheism. The words of Tawhīd: La illah illa Allah (there is no god but Allah) is a means to enter Paradise.
2) We should be keen to make the words of Tawhīd “there is no god but Allah” the last thing that the dying person says. If he utters other words after it, we should remind him of it once again.
3) When we exhort a dying person to say the testimony of faith, we thus comply with the Prophet’s command and show kindness to the dying person. Nothing is better than reminding him of words whose price is Paradise.
