Musnad Ahmad 1153:752

Surayj narrated to us, he said: Isa ibn Yunus narrated to us, from Ubayd Allah ibn Abi Ziyad, from al-Qasim ibn Muhammad, from Aisha, she said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever is scrutinized in the reckoning, he will not be forgiven." She said: I said: O Messenger of Allah, then where is His saying: {He will be judged with an easy reckoning} [Al-Inshiqaq: 8]? He said: "That is the presentation."
