Majma al-Zawaid — Hadith 11797

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) reports that the Prophet (peace and blessings be upon him) said: "When Allah Almighty created the pen, He said to it: 'Write!' So it wrote down whatever was to be until the establishment of the Hour."
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy). A hadith of this kind has already passed in the commentary on Surah "Nun", and another hadith will come later in the chapter on righteousness and maintaining ties of kinship, if Allah wills.
