One becomes ill, in i'tikaf or finds Haydh (menses)

“Abi ‘Abdillah (a.s.), has said: ‘If one in the state of I'tikaf becomes ill or a female begins to experience Haydh (menses); they can go home then after getting well perform the I’tikaf again and fast.’”

“Abu ‘Abd Allah (a.s.), has said, ‘If a female in Ttikaf begins to experience Hayd (menses) she must go home; and after becoming clean return to complete Qada’ (compensatory ’Ttikaf) of what she owes.’”
