ʿAtāʾ ibn al-Sāʾib, however, had suffered a deterioration in memory. It has also been narrated from him in other forms, which may be found in al-Majmaʿ (4/83), and al-Bukhārī cited it in suspended form (2/28). It is corroborated by a hadith from Jābir traced back to the Prophet. Al-Bayhaqī narrated it (5/347) through Abū al-Zubayr from Jābir. Its narrators are trustworthy, except that Abū al-Zubayr was known for concealing breaks in transmission, and here he narrated it merely with the formula “from.” Nevertheless, taken together, the two routes render the hadith sound—particularly since Sahīh Muslim (3/7) contains the following hadith of Abū Hurayrah, traced back to the Prophet:

“A Muslim has six rights over another Muslim: when you meet him, greet him with peace; when he invites you, accept his invitation; when he asks you for sincere advice, advise him sincerely; when he sneezes and praises Allah, invoke Allah’s mercy upon him; when he falls ill, visit him; and when he dies, follow his funeral procession.”

334 — (The Prophet (peace and blessings be upon him) said: “Muslims are bound by their stipulations.” Al-Bukhārī cited it in suspended form, while Ahmad, Abū Dāwūd, al-Hākim, and others narrated it with a connected chain.) p. 250

Authentic. It is fully sourced in al-Irwāʾ (1303).

335 — (The Prophet (peace and blessings be upon him) forbade bidding up prices without intending to buy. Agreed upon.) p. 250

Authentic. Al-Bukhārī (2/25), Muslim (5/5), Ahmad (2/108, 156), and others narrated it from Ibn ʿUmar. It is fully sourced in al-Irwāʾ (1318).

336 — (The hadith: “The Prophet (peace and blessings be upon him) forbade intercepting merchandise before it reached the market.”) p. 250

Authentic. It is narrated from Ibn ʿUmar that the Messenger of Allah (peace and blessings be upon him) forbade merchandise from being intercepted until it reached the markets. Muslim (5/5), Ahmad (2/142), and Ibn Mājah (2179) narrated it, and the latter’s wording is:
