I was going to type part of that, though you have left abit out, which is important, there are different chains for the narration I think, some are weak that was what i was going to point out.

4. This hadith was recorded by Ibn Hibban, al-Hakim, al-Nasa'i in al-Yawm wal-Laylah, al-Tabarani in al-Du'a and Al-Bayhaqi in al-Asma' wa l- Sifat. Al-Hakim graded it sahih, and al-Dhahabi was silent about it, usually indicating his approval. Similarly Ibn Hajar graded it sahih in Fath al-Bari 11:208, it has a slightly different chain of narrators with al-Tabarani and Abu Ya'la about which Al-Haythami said (al-Majma') "It is recorded by Abu Ya'la and its men are trutworthy, but among them thre is some weakness." Commenting on the chain of Ibn Hibban, 'Alush (Tashnif al-Adhan no.927) says, "Its chain is weak, Daraj Abu Sumah is weak in his reports from Abu al-Haytham." Ibn al-Mundhir listed Daraj Abu Sumah among the narrators who the hadith scholars differ over saying, "Abu Hatim declared him weak, as did al-Daraqutni and others, Ahmad said, 'His hadiths are rejected' al-Nasa'i said, 'Rejected'" Yet others considered him trustworthy like Yahya bin Ma'in (it seems that quotes from him are what al-Hakim depended upon according to Al-Mundhiri's comments in al-Targhib) and 'Ali bin al-Madini - and particularly al-Tirmidhi in case he reports from Abu al-Haytham (as in this case!). Likewise he was quoted for support by Ibn Khuzaymah. Al-Albani calls him the possesor and author of manakir (rejected hadiths) see al-Da'ifah 1:294 and 254. Al-Albani graded it weak in Da'if Mawarid al-Zaman no.295, as did Muqbil bin Hadi in al-Mustadrak no.1988.
At the start of the quote, when it says 'This hadith' the hadith refered to was:
There is however a more agreed upon authentic hadith with different wording that gives much of the desired meaning for the context of this point. 'Abdullah bin 'Amr bin al-'As narrated that the Prophet, peace and blessings be upon him, said; "When death visited Allah's Prophet Nuh, peace and blessings be upon him, he said to his son; 'I shall narrate to you the will. I command you with two things and I forbid you from two things: I command you with La ilaha illah Allah. Surely if the seven heavens and the seven earths were placed on a pan of a scale, and La ilaha illah Allah was placed on the other pan of the scale, they would give in to La ilaha illah Allah.." This hadith was recorded by al-Bukhari in Al-Adab al-Mufrad, Ahmad, Al-Bayhaqi in al-Asma', and also Al-Tabarani according to Al-Haythami who said, "This isnad is sahih." Al-Albani included it in al-Sahihah no.134, and Shaykh Muqbil bin Hadi included Ahmad's hadith in Sahih al-Musnad manma Laysa fi al-Sahihayn v.1 p.544 and he said, "This haith is sahih."
Abu Sa'id al-Khudri, may Allah be pleased with him, reported that Allah's Messenger, peace and blessings be upon him, said; "Musa (alayhi al-salam) said; 'O Lord! Teach me something I can remember you and call upon you with!' He, Glory and Exalted be He, said, 'O Musa! If the seven heavens and what is in them other than Me, and the seven earths were in a pan (of the Scale) and La ilaha illah Allah was in another pan, then La ilaha illah Allah would outwigh them.'" Recorded by Ibn Hibban and al-Hakim who graded it sahih.4
