Al-Matalib al-'Aliyah 3035 — Permission to write

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: "O Messenger of Allah (peace and blessings be upon him), I very much love to preserve your noble sayings (in my heart), but my heart cannot retain them (properly); so may I seek the help of my right hand (to write these sayings down)?" He (peace and blessings be upon him) said: "If you wish (then do so)."
The chain of this hadith is hasan (good); Ibn Abi Shaybah recorded it in al-Musannaf, and in it he (peace and blessings be upon him) gave Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) explicit permission to write down the blessed hadith.
