It is reported that Hafsah – Allâh be pleased with her – once said to her father (‘Umar, during his Caliphate):

Allâh has increased the provisions; if only you would eat better food than the food you eat now and wear softer clothes then those you wear now?! He said, “I will argue [against] you with your own self: Was not the condition of Allâh’s Messenger – praise and peace be upon him – such-and-such [when you were his wife]!?” He kept reminding her until she cried. He continued, “I have told you, by Allâh, I will share in their hard living (in this world, referring to The Prophet and Abû Bakr) so that I may partake in their good life (in Paradise).”

(1) Shaykh Abd Al-Rahmân Al-Farîwâ`î explains in his edition of Hunâd’s Al-Zuhd that this narration is sahîh if it is confirmed that Mus‘ab b. Sa’d heard it from Hafsah; otherwise its chain of transmission is mursal sahîh (i.e. it is authentic except there is a missing link between Mus’ab and Hafsah)
