It is narrated from Sayyiduna Ubayd (may Allah be pleased with him), who had the honour of being a Companion, that the Prophet (peace and blessings be upon him) said: "Faith has three hundred and thirty laws (shari'ahs); whoever fulfils any one of them will enter Paradise."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Isa bin Sinan al-Qasmali, whom Ibn Hibban and Ibn Khirash declared thiqah (trustworthy), while the majority declared him da'if (weak). As for the narrator named Abd al-Rahman bin Ubayd, I have not seen anyone who has mentioned him.
