Is the hadith authentic that a child who looks at their parents with compassion receives the reward of an accepted Hajj for each glance?

Summary

The hadith appears in al-Isma'ili's al-Mu'jam and al-Bayhaqi's Shu'ab al-Iman through two chains, those of Ikrimah and al-Dahhak from Ibn Abbas. The Ikrimah chain is weak because of criticised narrators, namely Muhammad bin Humaid al-Razi and Zafir bin Sulaiman. The al-Dahhak chain is very weak because it contains Nahshal bin Said, whose narrations were abandoned, and an unidentified narrator, so it cannot strengthen the Ikrimah chain. This weakness does not negate the virtue of being dutiful to parents established in the Quran and authentic hadith.
