I was with Ibn Umar when a freedwoman of his came and complained of the harshness of life, saying she wished to leave Madinah.He said to her, "Sit down. For I heard the Messenger of Allah ﷺ say, 'No one endures its hardship and severity without my being an intercessor or witness for him on the Day of Resurrection.'"
حدثنا إسحاق حدثني مالك عن قطن بن وهب أو وهب بن قطن الليثي شك إسحاق
كنت عند ابن عمر إذ أتته مولاة له فذكرت شدة الحال وأنها تريد أن تخرج من المدينة فقال لها اجلسي فإني سمعت رسول الله ﷺ يقول لا يصبر أحدكم على لأوائها وشدتها إلا كنت له شفيعا أو شهيدا يوم القيامة
Its isnad is sahih. Qatan (with two fathas) bin Wahb bin Uwaymir Ajda Laythi, his reliability was already established at 5372. Ishaq bin Isa's doubt about whether he was Qatan bin Wahb or Wahb bin Qatan carries no weight, for he is indeed Qatan bin Wahb without dispute, but Ishaq forgot his name and so could not state it with certainty. Yuhanis Abu Musa, the freed slave of Zubayr bin Awwam, is a trustworthy tabii. Nasai and others confirmed his reliability, and Bukhari gave his biography in al-Kabir 4/2/427. Yuhanis is spelled with a damma on the ya, a fatha on the ha, a doubled fatha-bearing nun, and ending with a sin.The hadith is in Muwatta 3:83, slightly longer than here. Muslim also narrated it likewise, 1:388–389, through the route of Malik. Bukhari narrated it in al-Kabir 4/1/190, in the biography of Qatan bin Wahb, abridged, through the route of Malik. Muslim, 1:389, narrated only the part attributed to the Prophet, with the wording "whoever bears patiently its hardship" and so on, through the route of Dahhak from Qatan. Tirmidhi narrated it, 4:373, at length with a different wording similar to this, through the route of Ubaydullah bin Umar from Nafi from Ibn Umar, and Tirmidhi said, a hadith sahih ghareeb. See also 5818, and see also what has already come in the Musnad of Saad bin Abu Waqqas, 1573.Al-lawaa means hardship and constriction of livelihood.
