"When one of you performs the Friday prayer, let him not pray anything after it until he speaks or leaves." Narrated by al-Daylamī (1/1/64) through the route of al-Ṭabarānī, narrated to us by Aḥmad ibn Rushdīn, narrated to us by Khālid ibn ʿAbd al-Salām, narrated to us by al-Faḍl ibn al-Mukhtār from ʿAbd Allāh ibn Muhib from ʿIṣmah ibn Mālik al-Khaṭmī as a marfūʿ ḥadīth. Al-Ḥāfiẓ remained silent about it in "Mukhtaṣar al-Daylamī." Its isnād is very weak; al-Faḍl ibn al-Mukhtār, as al-Haythamī said (2/195): "Very weak." It is attributed to al-Ṭabarānī's "Kabīr." I say: Aḥmad ibn Rushdīn is Aḥmad ibn Muḥammad ibn al-Ḥajjāj ibn Rushdīn ibn Saʿd Abū Jaʿfar al-Miṣrī. Ibn ʿAdī said: "They accused him of lying, and things were rejected from him." I say: But the ḥadīth is authentic, as it was narrated by Muslim in his "Ṣaḥīḥ" (882) and also by Ibn Khuzaymah (1/194/1) and others from the ḥadīth of Muʿāwiyah ibn Abī Sufyān (raḍiya Allāhu ʿanhu) as a marfūʿ ḥadīth. I have also extracted it in "Ṣaḥīḥ Abū Dāwūd" (1034).

"When one of you sneezes, let his companion say 'may Allāh have mercy on you.' If he sneezes more than three times, he is afflicted with a cold, and do not say it after that." Narrated by Ibn al-Sunnī in "ʿAmal al-Yawm wa-al-Laylah" (251) and Ibn ʿAsākir in "Tārīkh Dimashq" (2/391/2) from Sulaymān ibn Sayf, narrated to us by Muḥammad ibn Sulaymān ibn Abī Dāwūd: informed us by his father from al-Zuhrī from Saʿīd ibn al-Musayyib from Abū Hurayrah as a marfūʿ ḥadīth. I say: And this isnād, all its men are trustworthy except for Sulaymān ibn Abī Dāwūd, who is al-Ḥarrānī nicknamed (Būmah), as al-Dhahabī said: "Abū Ḥātim weakened him, and al-Bukhārī said: his ḥadīth is rejected. Ibn Ḥibbān said: he is not to be relied upon."
