Abdullah bin Abbas reported,
A man asked, "Messenger of Allah, what are the major sins?"He replied, "Associating partners with Allah, despairing of Allah's mercy, and giving up hope in Allah's compassion."
Azami 234
Hasanعن ابن عباس
أن رجلا قال: يا رسول الله ما الكبائر؟ قال: الشرك بالله، والإياس من روح الله، والقنوط من رحمة الله.

Bazzar narrated it - Kashf Astar (106) - from Abdullah bin Ishaq Attar, who said, "Dahhak bin Makhlad narrated to us, Shabib bin Bishr narrated to us, from Ikrima, from Ibn Abbas," and he related it.Haythami said in Majmaa (1/104), "Bazzar and Tabarani narrated it, and its narrators are trustworthy."Its chain is hasan because of Abdullah bin Ishaq Attar, who is Jawhari Basri, nicknamed Bidaa, the scribe of Abu Asim Dahhak bin Makhlad. Abu Hatim said, "A sheikh." Ibn Hibban mentioned him among the trustworthy narrators and said, "His hadith is sound." His teacher Shabib bin Bishr Bajali Kufi has hasan hadith.I did not find this hadith in the printed volumes of Tabarani.
