went out one day and performed over the martyrs of Uhud a prayer like the funeral prayer. He then turned toward the pulpit and said: “I shall go before you to the Pond, and I shall testify on your behalf. By Allah, I can see my Pond even now. I have been given the keys to the treasures of the earth—or the keys of the earth itself. And, by Allah, I do not fear that you will fall into polytheism after I am gone; rather, I fear that you will compete with one another over it.”

This is an authentic hadith with an elevated chain.
It was recorded by al-Bukhari, Muslim, Abu Dawud, and al-Nasa’i through multiple routes from Yazid (1).

11 – Ishaq ibn ʿAbd Allah, the son of the Companion of the Messenger of Allah ﷺ, Abu Talhah Zayd ibn Sahl al-Ansari
al-Khazraji, al-Najjari, al-Madani; a jurist and one of the reliable transmitters.

He heard hadiths from his uncle Anas ibn Malik, from Abu Murrah the freedman of ʿAqil, from al-Tufayl ibn Ubayy, from Saʿid ibn Yasar, and from others.

Those who transmitted from him include ʿIkrimah ibn ʿAmmar, Hammam ibn Yahya, Malik, Ibn ʿUyaynah, and many more.

Malik used to praise him highly and would place no one ahead of him.

His father, ʿAbd Allah, had his palate rubbed with dates by the Prophet ﷺ when his brother Anas carried him to the Prophet. Their mother was Umm Sulaym.
