Anas said, "I used to serve the Prophet, may Allah bless him and
grant him peace." He continued, "I used to enter without asking for permission
to enter. One day I came and he said, 'My son, there is a new situation.
You should not come in unless you have permission.'"
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: لاَ يَقُولَنَّ أَحَدُكُمْ: خَبُثَتْ نَفْسِي، وَلَكِنْ لِيَقُلْ: لَقِسَتْ نَفْسِي.
'A'isha reported that the Prophet, may Allah bless him and grant
him peace, said, "None of you should say, 'khabuthat nafsi'. He
should say, 'Laqisat nafsi.'"
As-Sa'b ibn Hakim reported that his grandfather said, "I came to
'Umar ibn al-Khattab, may Allah be pleased with him. He began to say, 'Nephew.'
Then he questioned me and I told him my lineage and so he knew that my
father had not become Muslim. He began to say, 'My son, my son.'"
