It is narrated from Sayyiduna Wathilah bin al-Asqa' (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, the greatest of lies is that a man lies about his own eyes, saying: I saw (a dream), when he did not see it; or that he lies about his parents; or that he says: So-and-so heard me, when he did not hear him." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah, the Mighty and Majestic, has not sent down any disease without sending down a cure for it. Whoever knows it, knows it; and whoever is ignorant of it, remains ignorant of it." This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Usamah bin Sharik (may Allah be pleased with him) that he said: I was present with the Messenger of Allah (peace and blessings be upon him) while the Bedouins were asking him (about various matters). They would say: O Messenger of Allah, is there any harm for us in such and such? Is there any sin for us in such and such? They were asking about things in which there was no harm. So he (peace and blessings be upon him) said: "O servants of Allah, Allah has removed harm (from minor slips), except for the one who wrongfully assails the honour of a Muslim, oppressing him; that is the one who has fallen into sin and is ruined." The Companions said: O Messenger of Allah, should we use medicine (in illness)? He (peace and blessings be upon him) said: "Yes, O servants of Allah, use medicine, for Allah Almighty has not created any disease without also creating a remedy for it, except for one disease." They said: O Messenger of Allah, which disease is that? He (peace and blessings be upon him) said: "Old age." Then they said: O Messenger of Allah, what is the best of all the blessings given to a person? He (peace and blessings be upon him) said: "Good character." This hadith has an authentic (sahih) chain of narration. Ten of the Imams of the Muslims and their trustworthy narrators have narrated it from Ziyad bin Ilaqah; among them is Mis'ar bin Kidam, whom I mentioned earlier, and among them is also Malik bin Mighwal al-Bajali.

Muhammad bin Mus'ab al-Qarqasani narrates, through Malik bin Mighwal, from Ziyad bin Ilaqah the same hadith whose text has passed under number 8406.

Amr bin Qays al-Mula'i has also narrated a report with the same meaning through Ziyad bin Ilaqah.

Sulayman bin Mihran al-A'mash has narrated the same hadith through Ziyad bin Ilaqah.

Shu'bah bin al-Hajjaj has transmitted this same hadith through Ziyad bin Ilaqah.

Likewise, with another similar chain, Imam Shu'bah has narrated this same report through Ziyad bin Ilaqah.

Muhammad bin Juhadah al-Iyadi has transmitted a narration through Ziyad bin Ilaqah in support of this same hadith.

Abu Hamzah Muhammad bin Maymun al-Sukkari has related the same hadith through Ziyad bin Ilaqah.
