Channah's song contains prophetic material relating to the nation as a whole. This approach subdivides regarding the time period to which the song refers:
The prayer relates to events throughout the nation's history from the defeat of the Philistines by the hand of Shemuel until the time of Mashiach.
"וַתִּתְפַּלֵּל חַנָּה" – Radak attempts to support this approach by claiming that the language of "תפילה" usually refers to events which are to occur in the future rather than to that which has transpired in the past. Nonetheless, it is still not the expected verb to connote prophecy, and is more fitting for a request.
Opening lines of praise – According to Targum Yonatan the various expressions of praise ("עָלַץ לִבִּי בַּיהוָה רָמָה קַרְנִי בַּי"י" etc.) do not represent Channah's own feelings, but rather the nation's future exultation after their victories over various foes.
References to enemies and imagery of war – Since much of the song relates to Israel vanquishing its foes, references to enemies is expected.
"שָׂמַחְתִּי בִּישׁוּעָתֶךָ" – Similarly, the language of "ישועה" is appropriate for this approach as Channah is speaking about actual salvation from enemies, and not just a granting of her request for a child.
Specific allusions – Targum Yonatan presents each of the song's opening verses as referring to Israel's salvation from a different enemy: the Philistines, Assyria, Babylonia, Greece, and Persia. However, the Targum only loosely links the words of the text with the event alluded to. Thus, for example, it connects the phrase "אֵין קָדוֹשׁ כַּי"י" to the defeat of Sancheriv by saying that with his downfall all the nations will claim that there is none like Hashem. It connects the war against Greece with the verse "קֶשֶׁת גִּבֹּרִים חַתִּים וְנִכְשָׁלִים אָזְרוּ חָיִל" as the story is one in which the weak defeat the mighty.
Changing fortunes: "עַד עֲקָרָה יָלְדָה שִׁבְעָה" – Radak raises the possibility that the barren woman is a metaphor for Israel in distress, while the fruitful lady represents Israel's enemies. Channah prophesies that at some point, Israel will be the one to flourish while her enemies become desolate. This idea can be applied to the other examples of reversal of fortunes as well.
Watching over the righteous – According to Targum Yonatan verses 6-9 focus on the rewards and punishments of people in the next world.
Mention of a king – As this position claims that the whole prayer is prophetic, there is no problem speaking of a king even though Israel had as of yet to appoint a monarch. According to Targum Yonatan, however, the verse actually speaks not of Shaul or the Davidic dynasty but of the defeat of Gog and Magog and the Messianic era.
Relevance – One of the difficulties of this approach is its lack of relevance to the larger story. Why does Channah prophesy about all these events right now, and why is it being shared with the reader?
The entire song focuses on the time period of Shemuel, weaving present events with future actions to be done by the prophet.
Opening lines of praise – Ralbag maintains that Channah's happiness and praise stem not from Shemuel's birth but from his future actions as leader, when he will remove idolatry form the midst of Israel and vanquish the Philistines.
Reference to enemies – Channah speaks of the Philistines whom Shemuel will defeat.
"אַל תַּרְבּוּ תְדַבְּרוּ גְּבֹהָה גְבֹהָה" – Ralbag suggests that this part of the song refers back to the present, and Channah is aiming these words at Penina who had gloated about her children.
Changing fortunes – Channah speaks of the changing circumstances of mankind to explain why no one should ever be haughty in their success (or despondent in troubled times) since Hashem can reverse such fortune overnight.
"י"י יֵחַתּוּ מְרִיבָיו עָלָיו בַּשָּׁמַיִם יַרְעֵם" – These words are a request that Hashem help Shemuel defeat the Philistines from on high, and are fulfilled in Shemuel I 7, as written there: "וַיַּרְעֵם י"י בְּקוֹל גָּדוֹל בַּיּוֹם הַהוּא עַל פְּלִשְׁתִּים" .
"יָדִין אַפְסֵי אָרֶץ" – This refers to Shemuel's future role as Judge.
Mention of king: "וְיִתֶּן עֹז לְמַלְכּוֹ וְיָרֵם קֶרֶן מְשִׁיחוֹ" – Channah prophesies regarding Shemuel's anointing of both Shaul and David.
20 Relevance – Since all of Channah's prophecies relate to Shemuel directly, it is understandable why they might be spoken of right now.
