Imām Muḥammad b. Idrīs al-Shāfi’ī (d. 204 AH رحمه الله) said [in al-Risālah]:
فَلَيْسَتْ تَنْزِلُ فِي
أَحَدٍ مِنْ أَهْلِ دِينِ اللهِ نَازِلَةٌ إِلَّا وَفِي كِتَابِ اللهِ الدَّلِيلُ
عَلَى سَبِيلِ الْهُدَى فِيهَا.
“No crucial issue (nāzilah) befalls anyone among the people of Allah’s religion except that
the Book of Allah contains evidence providing guidance regarding it.”
Translated by Umar Quinn (hafidhahullah)
Ibnul Qayyim رحمه الله said:
You must ensure that you only care about one thing – namely working
for the pleasure of Allah alone, for indeed it is the ultimate
happiness that a servant of Allāh can ever dream of having.

said:
“Whoever worships Allah the Most-High for one thousand
years, then associates partners with Allah for a moment and then dies upon that, all of his deeds will be
destroyed, and they become scattered floating particles.”

Ibn Wahb said that Ibn Mahdee informed him that a man asked Ibraaheem an-Nakha'ee about al-ahwaa' [i.e. bid'ah], do they have anything from khayr? So he said: "Allaah did not make in anything from it (even the amount equal to) a mustard seed of khayr, and it is nothing but an adornment from ash-Shaytaan, and the affair is nothing except the first affair [that which the Prophet (Sallallaahu ‘alayhi wasallam) and his Companions were upon]."
