«ما من ولد بار ينظر إلى والديه نظرة رحمة، إلا كتب الله له بكل نظرة حجة مبرورة قالوا: وإن نظر كل يوم مائة مرة؟ قال: نعم. الله أكبر وأطيب»
Ibn Abbas (radi Allahu anhu) narrated that the Prophet (sal Allahu alaihi wa sallam) said: “The pious offspring who casts a single look of affection at his parents receives a reward from Allah equal to the reward of an accepted Hajj.” The people enquired: “O Prophet of Allah (sal Allahu alaihi wa sallam), if someone casts a hundred such glances of love and affection at his parents, what then?” The Prophet (sal Allahu alaihi wa sallam) said: “Yes, indeed, even if one does so a hundred times a day, he will get a hundred fold reward. Allah is far greater than you imagine and is completely free from petty narrow mindedness.” [Sahih Muslim]

This hadeeth is in fact a fabrication as stated by Imam Dhahabi and Shaykh Al-Albani, and it is not recorded in shahih Muslim. Rather it is to be found in Shu’ba al-emaan of Imam Bahaqi’s collection.

Can you translate what the last two links say, regarding the authenticity of the hadith?

Shyakh Al-Albani called it Mawdoo’ and Imam Dhahbi declared it Munkar. Basically its a fabrication on the Rasool (SAW)
