Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates a marfu’ tradition regarding the statement of Allah Almighty «‏‏‏‏وَإِن كُنتُم مَّرْضَىٰ أَوْ عَلَىٰ سَفَرٍ» ‏‏‏‏ [ سورة النساء ] “And if you are ill or on a journey,”that if a Muslim person is wounded in the path of Allah Almighty, or he develops boils or abscesses, or he is afflicted with smallpox, and he becomes in a state of janabah, and he fears death if he performs ghusl, then he should perform tayammum. Imam Abu Bakr (may Allah have mercy on him) says that no one except Ata bin Sa’ib has narrated this tradition as marfu’.
