Muhammad ibn Waas’ رحمة الله, narrated:
“A man from the people of Basrah traveled to Umm Zhar, may Allah be pleased with her, after the death of Abu Zhar Al Gifari, may Allah be pleased with him, and asked her about how Abu Zharr would worship, and so she replied:
‘He would spend most of his day in a corner of the house, contemplating.’”
Al-Hasan, may Allahﷻ have mercy upon him, said:
"He whose words are not those of wisdom, his silence is not spent in contemplation and his observations are not to take lessons. Such a person is heedless and is squandering his time.”
He, may Allahﷻ have mercy upon him, said regarding the one hundred and forty-sixth verse of chapter Al-A’raf in which Allahﷻ says:
سأصرف عن آياتي الذين يتكبرون في الأرض بغير الحقwhich means:
“I will turn away from My signs those who are arrogant upon the earth without right…”
[Surah Al-A’raf: Ayat 146]
that it means "I (i.e., Allahﷻ) will prevent their hearts from contemplating.”
