Hadith 1426
´It was narrated from Tamim Dari that the Prophet (ﷺ) said:` “The first thing for which a person will be brought to account on the Day of Resurrection will be his prayer. If it is complete, then the voluntary (prayers) will also be recorded for him (as an increase). If it is not complete then Allah will say to His angels: ‘Look and see whether you find any voluntary prayers for My slave, and take them to make up what is lacking from his obligatory prayers.’ Then all his deeds will be reckoned in like manner.”
Hadith 2612
´Muslim bin Haisam narrated from Ash'ath bin Qais who said:` “I came to the Messenger of Allah (ﷺ) with a delegation from Kindah, and they thought that I was the best of them. I said: 'O Messenger of Allah (ﷺ) are you not from among us?' He said: 'We are the tribe of Banu Nadr bin Kinanah, and we do not attribute ourselves to our mother and we do not deny our forefathers.'”He said: “Ash'ath bin Qais used to say: 'If any man is brought to me who suggests that a man from Quraish does not belong to Nadr bin Kinanah, I would carry out the legal punishment (for slander) on him.'”
