Hadith on Hereafter: You do not know the status of those who died

Anas reported: A man among the companions of the Prophet passed away and another man said, “Receive glad tidings of Paradise!” The Messenger of Allah, peace and blessings be upon him, said, “Certainly you do not know, for perhaps he spoke of what does not concern him or he was miserly with what would not disadvantage him.”

عَنْ أَنَسٍ قَالَ تُوُفِّيَ رَجُلٌ مِنْ أَصْحَابِهِ فَقَالَ يَعْنِي رَجُلًا أَبْشِرْ بِالْجَنَّةِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَوَلَا تَدْرِي فَلَعَلَّهُ تَكَلَّمَ فِيمَا لَا يَعْنِيهِ أَوْ بَخِلَ بِمَا لَا يَنْقُصُهُ
