Riyad as-Salihin, 595

'Atiyyah bin 'Urwah As-Sa'di (May Allah be pleased with him) reported:

Messenger of Allah (ﷺ) said, "No one will attain complete righteousness until he abandons (certain) unobjectionable (but doubtful) things so as to remain on his guard against something objectionable." <b>[At-Tirmidhi, who classified it as Hadith Hasan]</b>.

وعن عطية بن عروة السعدى الصحابي رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم‏:‏ ‏

‏لا يبلغ العبد أن يكون من المتقين حتى يدع مالا بأس به حذرا لما به بأس‏

‏‏.‏ ‏(‏‏(‏رواه الترمذى وقال‏:‏ حديث حسن‏)‏‏)‏‏.

<b>Guidance from the Hadith:</b><br> 1) It is part of perfect piety and certitude to give up what is lawful but involves doubt for fearing of committing what is unlawful.<br> 2) If a lawful thing is mixed with an unlawful one, we should avoid it all. This is because we are required to avoid anything unlawful, which cannot be done in such a case without avoiding the entire matter.
