Engaging in the remembrance of Allaah

Is it permissible to engage in the remembrance of Allaah whilst not in a state of wudhoo – such as [when uttering the] takbeer [الله أكبر], tahleel [لا إله إلا الله] and tahmeed [الحمد لله], as well as sending prayers and salutations upon the Messenger (sal-Allaahu ‘alayhi wa sallam)?

Forwarding Islaamic messages via mobile phones

In this present time of ours, and in particular [I wish to ask about the issue related to] mobile phone messages (SMS, WhatsApp etc.) which we receive quoting ahaadeeth, and at the end it states: ‘Forward this message, and you will be rewarded in like or more [plentifully]’. So what is your opinion regarding forwarding some of these ahaadeeth, particularly since we do not know their authenticity?
