And they brought his shirt with false blood. Yaqoob said: "Rather, your souls have tempted you to do something, so it is most appropriate for me to be patient, and Allah is the One to Whom I seek for help against whatever you are describing".
Yaqoob had the Knowledge about the Three-Time-Knower Lord’. That means Yaqoob knew that nothing happens in the universe without the Knowledge of the Lord and nothing is left without it is being inscribed in His Book Adhikr as explained in verse 10: 61. So he entrusted upon Lord with patience.
Adhikr is formed as the Splendid Book today. Through verse 22: 78 it is told by calling the believers: "You holdfast Allah, He is your Master, what a Best Master and what a Best Helper". Since Adhikr is the Unbreakable Rope extended from the Paradise, whoever holdfast It, he did holdfast Lord and is guided into the Straightpath as explained in verses 2: 256; 3: 101 and 5: 48. See explanation 2: 153-157; 5: 94 and 9: 51.
